--- Comment #3 from Marco Castelluccio <mcastelluccio at mozilla dot com> --- > Thanks for the report Marco. Looks it comes from Firefox, am I right? Yes, that's correct. Actually, from a build of the JS shell. > Which version of GCC have you been using? The build was done with "gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609". We were also able to reproduce the crash with a gcda generated normally, without __gcov_dump.
