The warning must be due to the inline fstat() implementation in
mingw-w64. Excerpt from stat.h:
__CRT_INLINE int __cdecl
fstat(int _Desc,struct stat *_Stat) {
struct _stat64 st;
int ret=_fstat64(_Desc,&st);
if (ret == -1) {
memset(_Stat,0,sizeof(struct stat));
return -1;
}
/* rest of the code */
Note that the memset() in the failure case was only recently added in our svn,
at rev. 1306, so this warning shouldn't be experienced with mingw-w64 rev.1306
or later. Older revisions didn't touch the input buffer on failure which should
be the reason for the warning.
