LLDB crash

The crash dump says the pointer is pointing to a gap in the VM space of size 0x4000.Here's a bit more data:Process 626 stopped * thread #12, stop reason = EXC_BAD_ACCESS (code=1, address=0x106941224) frame #0: 0x00000001006e72a0 iSH`cpu_run [inlined] __mem_read(mem=<unavailable>, addr=<unavailable>, size=4) at memory.h:105 [opt] 102 void *ptr = __mem_read_ptr(mem, addr); 103 if (ptr == NULL) 104 return false; -> 105 memcpy(out, ptr, size); 106 return true; 107 } 108 #define mem_read(mem, addr, value) __mem_read(mem, addr, (value), sizeof(*(value))) Target 0: (iSH) stopped.

But what if I don't download the archive builds from Xcode Cloud and don't have them locally? Does that mean that I won't be able to symbolicate crash? I thought the crashes would be symbolicated in the cloud. It's not the case? When you submit your app to the App Store, there's an option for you to include symbol information as part of the app for that upload. When you do so, crash reports that appear in your Xcode Organizer for that app version will be symbolicated for you already. That's a feature of the App Store, and not specific to builds created and uploaded through Xcode Cloud. However, that doesn't mean you shouldn't download the archives from Xcode Cloud, that is still a best practice. One valuable part of that is access to the dSYMs, which are incredibly detailed debugging assets. While using the dSYMs for symbolication is one function they serve, they also enable significant debugging capabilities using LLDB that aren't possible without them. The symbol informat

I have the same problem like here for Xcode 10 GM and OS High Sierra 10.13.6, SWIFT 4.2https://stackoverflow.com/questions/43977271/lldb-couldnt-irgen-expression

I would like to be able to start debugger using process name and launch the extension and be able to debug from first line of code in extension. Due to the way that sysexes are loaded — they are very different from apexes! — I would not expect to be able to attach before the process is running. However, you wrote: If the extension is already running, then I am able to attach by PID but never by name. and I would expect name and PID to work equally well here, that is, they both work or they both don’t. That fact that’s not the case is weird. I have tried using target name as well as extension bundle identifier and several other combinations. Try this… Run lldb using sudo. % sudo lldb Type in this command: (lldb) process attach -n *** but don’t press Return. In this context *** is the name that you successfully attached with in the past. Press Tab. LLDB should print a list of candidates. Copy the full expansion of the sysex name. Go to Xcode and enter that into Debug Attach t

How did you manage to get the CoreBluetooth security confirmation appear for your command-line app? I'm trying to do the same and said alert only appears when I run the app from lldb.

Regarding Instruments:It may not be an error, but the options for the top level summary may (in effect) be different from those for your detail view. The top level might be including all objects ever created and/or destroyed, while the detail might only be show objects still in existence at a certain time.If you can't find an explanation, or if there might be an explanation but you think it's too confusing, then submit a bug report and attach your Instruments document.Regarding dSYMs:>> if lldb can do it, you can too!Actually, it's always lldb, not Xcode. Xcode uses lldb as its interface to debugging generally.As to missing debug information, it's a bit complicated. In a release build, all debugging information has been moved to a dSYM, and the executable contains nothing to help debugging, except module names and global symbols.In a debug build, the debug information (last I heard) can be spread around multiple locations, according to the technical needs of various binary for

Same problem here with Xcode 8.0 (8A218a)expression produced error: /var/folders/pv/5jlpdzzn3p55w0ynccpt8x500000gn/T/lldb/37283/expr139.swift:1:53: error: 'XCUIElement' is not a member type of 'XCTest' $__lldb__DumpForDebugger(Swift.UnsafePointer<XCTest.XCUIElement>(bitPattern: 0x119244860).memory) ~~~~~~ ^ /var/folders/pv/5jlpdzzn3p55w0ynccpt8x500000gn/T/lldb/37283/expr139.swift:1:45: note: while parsing this '<' as a type parameter bracket $__lldb__DumpForDebugger(Swift.UnsafePointer<XCTest.XCUIElement>(bitPattern: 0x119244860).memory)The file expr139.swift content is :$__lldb__DumpForDebugger(Swift.UnsafePointer<XCTest.XCUIElement>(bitPattern: 0x119244860).memory)

So here's a capture from dlopen/dlclose() of the same library renumbered at the end. The path doesn't change, and it's looks like the cache restores the original 000.dylib instead of the 001.dylib that dlopen() requested on the second call. I have dyld environment settings providing a little more insight here. (lldb) image list -b [621] other.dylib [622] other2.dylib dlopen(/foo/bar_signed_000.dylib) dyld: Mapping /foo/bar_signed_000.dylib dyld: loaded: /foo/bar_signed_000.dylib (lldb) image list -b [621] other.dylib [622] other2.dylib [623] bar_signed_000.dylib <- correct, it’s loaded and in the list dlclose() dyld: unloaded: /foo/bar_signed_000.dylib <- correct, unloaded dlopen(/foo/bar_signed_001.dylib) dyld: loaded: /foo/bar_signed_001.dylib <- dyld reused the UUID? (lldb) image list -b [627] bar_signed_000.dylib <- ugh, this is wrong path
