| SYMPTOM:
memory overrun char array written beyond its size.
SOLUTION:
In file: scandir_win32.c
replace-> selectDir=(struct dirent*)malloc(sizeof(struct
dirent)+strlen(find.cFileName)+1);
by -> selectDir=(struct dirent*)malloc(sizeof(struct
dirent)+strlen(find.cFileName)+2);
EXPLAIN:
This happens when then following condition is met:
if (find.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
// Append a trailing slash to directory names...
strcat(selectDir->d_name, "/");
because we concatenate a slash we need one more char ....
