Hi @Taeung
The uftrace doesn't handle the bug and always shows duplicated functions. The __cyg_profile_func_enter receives two argument - "child" and "parent" which are passed by rdi (edi) and rsi registers respectively. First call is for child 0x400626 (main function) and the second is for child 0x400500 (open function). And then the open function was printed (again) by the PLT hooking code.
I'm not sure it's worth to handle this kind of bug in uftrace.

@namhyung , I understood the reason of duplicated open() you expain.
And I also think it isn't needed to handle this bug in uftrace, as you said..
Close this issue ?
