Maybe try getting a back trace without debug symbols. It won't be as useful, but it should cut down on the memory usage for linking. Just perform the same procedure, but leave -g and -ggdb out of your CFLAGS. OK, so I have removed -ggdb from my CFLAGS, leaving -O1 as the only change. I have added 'nostrip' to FEATURES (although now I have removed -ggdb I am not convinced this is required). I have successfully recompiled. Which executable should I run from gdb? Trying /usr/bin/chromium and /usr/bin/chromium-browser gave "/usr/bin/chromium": not in executable format: File format not recognized and "/usr/bin/chromium-browser": not in executable format: File format not recognized (In reply to comment #6) > Which executable should I run from gdb? /usr/lib/chromium-browser/chrome [5011:~]$ gdb /usr/lib/chromium-browser/chrome GNU gdb (Gentoo 7.3.1 p2) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

It does lead me to guess that chromium is crashing when some shared library is being loaded. Perhaps one of them is corrupt. If you have the time and patience, you could get a list of shared libraries using ldd /usr/lib/chromium-browser/chrome, and map those to packages using the qfile command. Then you could rebuild each library until chromium stops segfaulting (hopefully). Another idea would be to run strace /usr/lib/chromium-browser/chrome to see if we can determine which library is being loaded when the segfault happens. Created attachment 317746 [details]
Output from strace
I'm out of ideas for now. Chromium now working again after a recent emerge -auvD world followed by revdep-rebuild. No idea what the root cause was. |
