I'm posting that bug here since I need some advices. With gdb 6.x all was fine. With >=7, if I do: gdb firefox, all that I get is: [...] Reading symbols from /usr/bin/firefox...(no debugging symbols found)...done. (gdb) run Starting program: /usr/bin/firefox (firefox:4728): GLib-WARNING **: g_set_prgname() called multiple times Program received signal SIGBUS, Bus error. 0x29160ae2 in ?? () (gdb) If I let it coredump and do: gdb --core firefox.core firefox, all is fine, I get the debug information I wanted. As I am not familiar with the codebase, I failed to understand where to look for what has been broken...
probably going to sit more on the BSD side of things to resolve. best bet is to just e-mail the gdb lists about it and ask for advice there.
I assume there was no followup. Let's close as obsolete.
