M1. Instrument Leaks error "Failed to gain authorization" (C program)

This should work. As a diagnostic test, build a small test tool in Xcode and see if leaks works with that. That’ll tell you whether the problem is caused by your compiler or by your leaks setup.

I wonder if I can use leaks with programs that are not compiled in Xcode?

Xcode is not in a privileged position when it comes to building and signing code. Anything it does should be achievable by other development tools.

In the build logs, I see the steps: Sign <appname> Register execution policy exception for <appname>

This is a red herring. Xcode is registering its newly built code with the Execution Policy framework but that is a no-op on current systems [1].

After reading this thread, I'm guessing it's about code signing.

Yes, that’s most likely. Try this:

1. Create an entitlements file with the com.apple.security.get-task-allow entitlement:

   % /usr/libexec/PlistBuddy -c "Add :com.apple.security.get-task-allow bool true" tmp.entitlements
   File Doesn't Exist, Will Create: tmp.entitlements

2. Sign your code with that entitlements:

   % codesign -s - --entitlements tmp.entitlements -f /path/to/tool
   xxst: replacing existing signature

Does that help?

[1] That might change in the future, of course, but I’ve no info to share on that front.

Hello, I have the same problem and could not resolve it. What is "/path/to/tool" ?

I have already reinstall my mac, I use the Xcode version 15, I tried to delete and reinstall Xcode. Nothing is working.
