Note: the bug I first wanted to report is different, I only encountered the ICE
in the process.
Should I open a new bug report with the content following?

------- Comment #3 from ibolton at gcc dot gnu dot org  2010-09-21 14:40 -------
Which architecture/cpu are you wanting to build for?  I'm not sure what the
default is.  If you can specify that when you configure, and then post the
outcome of the build, that would be helpful.

------- Comment #4 from rafael dot carre at gmail dot com  2010-09-21 15:20 -------
Same output with -mcpu=arm926ej-s or -mcpu=arm7tdmi

What did you mean with "when I configure" ? I posted gcc -v output, should I
rebuild gcc with a specific option?

I build with
http://www.rockbox.org/gcc/rockbox-multilibs-noexceptions-arm-elf-eabi-gcc-4.4.2_1.diff
to disable support for exceptions and build libgcc for several CPUs
