 Posted: Mon Mar 12, 2012 9:33 am Post subject: [SOLVED] Firefox/glib segmentation fault |
 |
|
Since upgrading my system to a sandy bridge i5 2500k, and doing a recompile, firefox immediately segfaults when run. Removing .mozilla doesn't help, nor does running in safe mode. Here's the output when running with gdb:
| Code: |
(gdb) run
Starting program: /usr/bin/firefox
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
[New Thread 0x7fffe2044700 (LWP 4932)]
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff0a1a748 in g_utf8_validate () from /usr/lib64/libglib-2.0.so.0
|
Not compiled with debugging symbols, but I did try it earlier and found no change in the message. I've tried recompiling my whole system but no change. Also tried recompiling glib with basic flags "-O2 -pipe". Firefox and xulrunner themselves filter cflags (including avx) so that shouldn't be an issue. In addition, I have a binary copy of mozilla's Prism, which also segfaults. There were a few failed packages after running "emerge -e world" but none were dependencies for firefox.
Here's my "emerge --info":

Cflags are relatively minimal and worked fine on older system (s775 core 2 duo). Glibc 2.15 is installed, but the issue also occurred with 2.14.1.
Next I will try compiling the entire system with basic cflags, and remove "-march=native" or downgrade it to something basic. But if there is anything obvious going on here, please let me know.
EDIT: Tried disabling CCACHE and that didn't help

Not sure how to interpret this, will look closer lately. Will probably need debugging symbols to do this right, correct? I'll try that out later. |

Okay, a proper backtrace:

(gdb) run

warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?

Does this look like the issue?

Will post a "bt full" backtrace if that would be useful. |

It says "optimized out", so I'm recompiling with "-O1 -ggdb -pipe". Will try with "-O0" if that message still comes up. |

any reason for all theses compilation options?
| Code: | | -fweb -fno-ident -ftree-vectorize -floop-interchange -floop-strip-mine -floop-block |

Just some additional optimisation. "-fweb" is pretty safe IIRC just a mildish optimisation that hurts debugging (certainly no issue on my older system) as are "-ftree-vectorize" (all packages that are affected by this filter it out) and "-fno-ident" (this one is very minimal). The last three are graphite optimisations, which I've never had any issue with.
I've been using various minimal flags for testing, however:
| Code: |
-march=native -O2 -pipe
-O2 -pipe
-O2 -pipe -ggdb
etc
|
I've still yet to compile entire system with basic cflags, however. |

I fixed it by unmerging gconf, removing all files from /etc/gconf, ~/.gconf, and ~/.gconfd, and then reemerging gconf. Everything works okay now  |

I'm having the same problem as OP.
Background: I had a ThinkPad T60 using an Intel Core2Duo T7200. Then I switched to a ThinkPad T400 with an Core2Duo P8400. The P8400 supports SSE4.1 while the T7200 does not. I simply swapped the hard drive and booted the T400. I then recompiled system (still running) and now firefox and thunderbird (maybe some more) don't start anymore.
Searched for bug reports but didn't find any.
Hope the "instructions" help me, too. Otherwise I'll do some more investigating. |

Ok, since I'm unable to fix the problem (and no one else on IRC seems to be able) this will be a bug report soon :/
UPDATE: I changed me CFLAGS from march=native to march=core2 and started an "emerge -1eav @system". After about 40 packages (out of 889), firefox started up fine again. Don't know which one it actually was.
UPDATE2: It's not the CFLAGS. I got the same problem again with march=core2 after merging some gnome-stuff-dependencies. Follow-up: https://bugs.gentoo.org/show_bug.cgi?id=408857 |

Hi
I got the same segfault and removing /etc/gconf and rebuilding gconf worked |

I got the same problem, now in firefox 19.
I tried the gconf delete e emerge, crossdev is up to date, even an orbit and gconf rebuild did not help.
LANG="C" firefox also does not work.
Anyone found a solution that works? |

| Rebuilding gconf and clearing the gconf directories worked for me too - thanks for posting this fix. |
