$ ltrace -o assertion.log -f eog ~/runtest.svg ltrace: breakpoints.c:41: address2bpstruct: Assertion `proc->leader == proc' failed. Aborted (core dumped) I am bit puzzled, is it sort of feature in ltrace to exit the same way trace app does, or is it a bug?
Created attachment 572246 [details] A fix This is a bug in ltrace. It happens when the application gets SIGSEGV and ltrace tries to figure out whether it's real or whether it signals a breakpoint. Apparently we didn't test the case where non-leader thread in a multi-threaded process dies of SIGSEGV ;)
Hmm, this is in fact a multi-threaded support bug, so I'll close this as duplicate. *** This bug has been marked as a duplicate of bug 742340 ***
