bootstrap failure while compiling gcc/tree.c

[Brian Sidebotham]

../../gcc/gcc/tree.c: In function "build_string":
../../gcc/gcc/tree.c:1197: internal compiler error: in iterative_hash_expr, at 
tree.c:4189
Please submit a full bug report,
with preprocessed source if appropriate.

I have placed the pre-processed file here:
http://www.valvers.com/gcc/arm-elf/tree.i (1.5Mb)

The following configure line was used:

../gcc/configure --target=arm-elf --prefix=${installdir} --with-newlib 
--with-headers=${newlibdir}/src/newlib/libc/include --enable-languages=c,c++ 
--enable-interwork --enable-multilib

codebase is svn revision 127732

The failing command line is:

gcc -c   -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -W -Wall -Wwrite-strings 
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition 
-Wmissing-format-attribute -fno-common   -DHAVE_CONFIG_H -I. -I. -I../../gcc/gcc 
-I../../gcc/gcc/. -I../../gcc/gcc/../include -I../../gcc/gcc/../libcpp/include 
-I../../gcc/gcc/../libdecnumber -I../../gcc/gcc/../libdecnumber/dpd 
-I../libdecnumber    ../../gcc/gcc/tree.c -o tree.o

and lastly, the specs of the gcc compiler being used are:

Using built-in specs.
