Hi,

binutils-gold is crashing while compiling chromium[1]. This was originally found on Debian[2], but affects ubuntu[3] as well. Also, regular, non-gold ld will segfault with null pointer reference on the same linking commands. testcase:

# wget http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=10%3Bfilename=allcodecs.o.x... # unxz allcodecs.o.xz # sha1sum allcodecs.o f7c93a9132e4d02a651ade8db9f7b3f76918d236  allcodecs.o # ld.gold allcodecs.o ld.gold: internal error in value_from_output_section, at ../../gold/reloc.cc:1516

according to report, not reproducible inside qemu.

Hi Riku. I'm afraid I can't reproduce this on my PandaBoard using a build from the end of last week:

This is with binutils-20110610+git4725c92[1] which is one of my weekly git builds. binutils was configured the same as Ubuntu using gcc-linaro-4.6-2011.05. See the host.txt[2] in the same directory for more information about the environment.
