I have recompiled mozilla-firefox with the debug flag enabled and according to the docs here: http://www.gentoo.org/proj/en/qa/backtraces.xml It looks like netscape-flash causes it to crash on some sites. I've attached the backtrace.
Created attachment 140513 [details] backtrace.log
Created attachment 140514 [details] emerge --info
Apart from the fact that we cannot fix flash at all, which sites?
I've had it crash on such sites as Youtube and a for-pay site that I use (you need a subscription to access the part I have trouble with).
CFLAGS=-g CXXFLAGS=-g FEATURES=splitdebug emerge www-client/mozilla-firefox That should give a far better backtrace inside gdb :-)
Created attachment 140921 [details] backtrace.log I compiled Firefox with what you suggested (similar to what I did) I ran code listing 1.4 from here: http://www.gentoo.org/proj/en/qa/backtraces.xml I got slightly more info this time.
#6 0xaf9c0560 in ?? () #7 0xafa16020 in ?? () #8 0xb0bd2938 in ?? () from /opt/netscape/plugins/libflashplayer.so #9 0xb0de30cd in ?? () from /opt/netscape/plugins/libflashplayer.so #10 0xb0dfa4f2 in ?? () from /opt/netscape/plugins/libflashplayer.so When I think about, I will guess that the stack has been trashed (buffer overflow), since the pointers at #6 and #7 is not mapped from a file (you can check if they are mapped at all by viewing /proc/<PID>/maps ). And if that is the case, then the crash happens inside the flashplugin which is closed sources and beyond what we can fix here.
