Segmentation fault with LD on Xcode 8.3 beta 3
| Originator: | macmade | ||

LD crashes with a segmentation fault when trying to link a macOS framework target.
> clang: error: unable to execute command: Segmentation fault: 11
> clang: error: linker command failed due to signal (use -v to see invocation)
Full LD invocation can be found in the attached crash report.
--------------------------------------------------------------------------------
I cannot attach the project that fails, as it's proprietary code.
The project is quite complex and huge, mixing C, C++ and Objective-C, with many external static libraries.
The crash occurs every time.
Based on the crash stack trace, I also tried to modify the LTO options with every possible value (none, incremental, monolithic), but LD still crashes.
Note that Xcode 8.2.1 works just fine...
--------------------------------------------------------------------------------
Crash always occurs on Xcode 8.3 betas...

All right, so the issue is still present with Xcode 9 beta (9M136h).
The good news is I’ve been able to reproduce the issue on a test project (attached here).
I’m not really sure what triggers the crash. Project setup is a bit weird, with some third-party code (libgpod) compiled to a framework inside another framework.
Also, this third-party library depends on glib, and as it’s a real pain to compile, we decided to reimplement the needed functions. So obviously some nasty code is involved here…
Attached project contains two scheme. The ASAN one is the faulty one. Hope it will be easier to spot the crash now! : )
Additional info: the crash is only present when the address sanitiser is turned on.
Well, no, sorry... Crash is still present in 8E162. But I think I can maybe find the reason... I'll provide more info...
Issue is no longer present in Xcode 8.3 8E162. Thank you!
New crash report is attached. Tell me if I can do anything to help solving this issue.
