How to debug static initialization problems?

Asked 2019-Aug-03 at 16:13

I'm having a hard time debugging this issue: https://github.com/cnjinhao/nana/issues/445

I have previously asked about LTO vs static object initialization and edited the library's code to implement Meyer's singletons so that the correct order of initialization happens. Hello worlds still crash, although library's functions have mostly dissappeared from stack traces:

The cause of the crash was that the nana library had -static-libgcc -static-libstdc++ in its CMake files as public dependency. The executable and all other libraries had them linked dynamically. Suprisingly, there were no symbol clashes but the standard library code in the executable was corrupted.

Solved by removing these flags from nana's CMake files.

uftrace used to remove some prefix in symbol demangler but it may confuse some users so I submitted a patch to keep it and it's merged now - https://github.com/namhyung/uftrace/pull/87

So if you update uftrace to the current master. You will see the first main() is now _GLOBAL__sub_I_main().

Thanks for your feedback!
