Notification Service Extension won't load if one specific framework is linked

If a Notification Service Extension contains no references to shared frameworks, it loads and works as expected.

It stops working completely when I add one particular shared framework to Linked Frameworks and Libraries section. The framework that causes issues seems to be not very different from others that work, except for its slightly larger size.

The same framework loads and works OK in any other extension I tried (Notification Content, Today Widget, Share).


Here's whats going on in the system log:

OK, these logs aren't helpful. Actually I was bumping in the memory usage limit for this kind of extensions. It's 5MB for Obj-C apps and 15 MB for Swift, App/Framework code included.

Yeah, I noticed my service extension usually died around 4.5 mb of objects allocated.
