--- Comment #4 from Jeffrey A. Law <law at redhat dot com> ---
Looks like reload writes offsets_known_at for a label on the
forced_labels_list. The problem is the label # of the offending label is 0,
but FIRST_LABEL_NUM is 4. This causes the out-of-bounds array accesses and
ultimately heap corruption.
