Kai Tietz <ktietz at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #8 from Kai Tietz <ktietz at gcc dot gnu.org> --- That is a MinGW.org issue. For mingw-w64 this issue is fixed. Well, actually it is under the hood a msvcrt issue about stat-routines. Sadly it can't handle proper trailing slashes on paths. To verify the issue simply check following test program: #include <io.h> #include <sys/stat.h> #include <stdio.h> int main() { struct stat fb; if (stat ("./", &fb)) printf ("'./' stat failed.\n"); return 0; } I close this bug as invalid, due it isn't caused, nor to be fixed by gcc.
