This can be fixed by setting the memory to 0 inside GetPathAttributes.
in utility.h line 48:
-GetPathAttributes(const char *,void *),
+GetPathAttributes(const char *,struct stat * )
In utility.c line 1152:
MagickExport MagickBooleanType GetPathAttributes(const char *path,
- void *attributes)
+ struct stat *attributes)
{
MagickBooleanType
status;
+ memset(attributes, 0, sizeof(stat));
btw I'm really not sure why GetPathAttributes took a void* before, it only seems to take a stat structure.
