(The original Fatal Trap notice reported the address in strcmp as well.) This suggests problems for the value in mp->md_cval (via modname) as of the strcmp call (based on where the Fatal Trap was reported to be at in strcmp). Note the mod->name argument to strcmp . Note that if mod-> could not be dereferenced, the failure would be before strcmp was called. Thus it looks to be the ->name value that strcmp ends up using that lead to the failure. Same sort of thing as for comment #82 (but a separate in-line). in strcmp it showed: 0xffffffff80cf0110 <+16>: movzbl (%rdi,%rcx,1),%eax So if you ever get a chance to have it report the %rdi value on an actual failure, the value may prove interesting. Of course, none of this gets far enough to suggest why the value of mod->name would be messed up. --=20 You are receiving this mail because: You are the assignee for the bug.=
