It's probably a conflict between msvcrt and glibc. The winegcc
documentation states that the -mno-cygwin flag "is necessary for the
vast majority of Win32 applications, as they typically depend on
various features of MSVCRT".[1] You could also compile your program as
an actual Windows EXE with `x86_64-w64-mingw32-cc test.c -o test.exe`.
