Re-emerging chromium has no effect on this issue
Is this by chance related to Bug 410777 ? What version of ICU do you have installed ? Have you tried removing your ~/.cache/chromium/ and ~/.config/chromium/ directories ?

A segfault in ld-linux.so is pretty weird. Here's a guide for getting better backtraces: http://www.gentoo.org/proj/en/qa/backtraces.xml ld-linux.so.2 is part of sys-libs/glibc, so you would need to rebuild that.

OK, I'll give that a try. Maybe I'll try re-emerging sys-libs/glibc first before applying the backtraces options.
Re-emerging glibc does not resolve the issue. Re-emerging chromium with the backtrace options set fails with: /usr/lib/gcc/i686-pc-linux-gnu/4.5.3/../../../../i686-pc-linux-gnu/bin/ld: failed to set dynamic section sizes: Memory exhausted I have 16GB of physical memory!! What now?
As I don't seem to ba able to emerge chromium with backtrace enabled I thought it might be helpful just to emerge glibc with bt. This does give some additional information but I don't know what to make of it. gdb /usr/lib/chromium-browser/chrome GNU gdb (Gentoo 7.4 p1) 7.4 Copyright (C) 2012 Free Software Foundation, Inc.

What now? I suspect you are running into the 2 GB per-process memory limit there. It is a bit odd for you to be running x86 on a Phenom II by the way. :) I don't have any thoughts on that backtrace, but maybe someone with some glibc knowledge might. I would like to wait for phajdan.jr to have a look and bring in an expert if he thinks that is appropriate.
Looking at your traces, I noticed the following: ------------------------------------------ open("/usr/lib/libnvidia-glcore.so.290.10", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\0RAL4\0\0\0"..., 512) = 512 [...] mmap2(NULL, 31701984, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xafa0d000 [...] mprotect(0xafa0d000, 31223808, PROT_READ|PROT_WRITE) = 0 --- {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x653a6315} (Segmentation fault) --- ------------------------------------------ The segfault occurs while accessing nvidia-glcore.so. Could you try upgrading your nvidia-drivers (and don't forget to eselect opengl and reboot). Have you checked other versions of chromium ?
I'm running x11-drivers/nvidia-drivers-290.10-r2. Later dirvers are broken, see bug 409247. I have been running this nvidia-drivers version since Feb 5 and I sure I've had chromium working at times between then and now. I guess it could be kernel related, I'm on sys-kernel/gentoo-sources-3.2.14. I try an older kernel & nvidia-drivers
I selected xorg-x11 opengl driver rebooted and chromium started OK. I reverted to the previous nvidia driver, x11-drivers/nvidia-drivers-290.10, selected opengl nvidia, rebooted and chromium started OK. I then installed the original nvidia driver, x11-drivers/nvidia-drivers-290.10-r2, selected opengl nvidia, rebooted and chromium still started OK. The issue has 'gone away'. Thanks for your help guys. The upside is I've learnt how to get backtraces.

Now converting to from 32 to 64 bit is non-trival. The issue has now gone away. See previous post.
