I not sure, Why "m" variable not initializes in with function
"fmap_check_empty(int fd, long offset, unsigned int len, int * empty) Line
138 + 0x13 bytes C"? I copy a stack traces call of function when clamscan
depend on debug mode.You should see below.

" if(!(mh = CreateFileMapping(m->fh, NULL, PAGE_READONLY,
(DWORD)((len>>31)>>1), (DWORD)len, NULL))) { "
