Jeffrey A. Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P1 CC| |law at redhat dot com --- 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.
