Hey, could you try making this change to File_Close in File+.c:
void File_Close(var self) {
FileData* fd = cast(self, File);
fclose(fd->f);
fd->f = NULL;
}And see if it fixes it.
Thanks.

It didn't help - the same result.

Perhaps you could also try this change to File_Delete in File+.c
var File_Delete(var self) {
FileData* fd = cast(self, File);
if (fd->f != NULL and tell(self) != -1) { close(self); }
return self;
}If that still doesn't work I'll wait till I can get to a Ubuntu machine and recreate the result.

It is now dying in test_file_read, but that doesn't mean it's still not due to corruption from the deletes in test_file_create. I'm on fedora 16 and gcc 4.7.2. Inspecting with GDB.

Had a bit of an inspection and I think Assignment and Copying are just too messy in implementation for File objects. Unless someone has a need for them later this can be considered a fix for now.
