"file is not a core dump" error with zlib compression #35
Description
I sometimes get a core dump that can not be read using corectl. It seems to happen only with gnome-maps and only when I have zlib compression enabled. I can read other core dumps fine. Disabling zlib compression and triggering the segfault again fixes this issue.
