$ 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?

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 ;)
Comment 5 Petr Machata 2012-03-23 11:35:31 UTC 
Hmm, this is in fact a multi-threaded support bug, so I'll close this as duplicate.
