It's caused by r162815:
http://gcc.gnu.org/ml/gcc-cvs/2010-08/msg00026.html

The build failure still occurs with r162878.

I'm not seeing this with my ARM cross-compilers.  Can you attach a .i file?

preprocessed source for _udivmoddi4

In non-parallel builds _udivmoddi4 is always the first module to make cc1 run
out of memory.  I get the error on both i686 and x86_64 hosts, and with both
gcc-4.4.4 and gcc-4.3.5 as bootstrap compilers (only tried 4.3.5 on i686
though).

I did use --with-arch=armv5te --with-tune=xscale when configuring my compiler,
which may be relevant as it changes instruction selection defaults.
