Bug 18055 – exception handling cause EXC_BAD_ACCESS when linking against shared libraries using vibe

I understand shared libraries are not 100% supported on OSX but they work to some extent and fullfill a use case; could we make sure this particular case works? It's sad that such a fundamental feature (shared libraries) still don't work in 2017. dmd --version DMD64 D Compiler v2.077.0 dub build mv libtest1.so libtest1.dylib # cf another dub bug which creates .so instead of .dylib dmd -g -of=app libtest1.dylib main2.d lldb ./app (lldb) r Process 85211 launched: './app' (x86_64) Shared libraries are not yet supported on OSX. ok1 Process 85211 stopped * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x90) frame #0: 0x00000001002fcfd1 libtest1.so`thread_stackBottom + 21 libtest1.so`thread_stackBottom: -> 0x1002fcfd1 <+21>: movq 0x90(%rcx), %rdx 0x1002fcfd8 <+28>: movq (%rdx), %rax 0x1002fcfdb <+31>: popq %rbp 0x1002fcfdc <+32>: retq Target 0: (app) stopped.
