Sig6 when compiling Newlib 1.8.0



When compiling Cygnus Newlib 1.8.0 for h8300-hms target on a RedHat 4.2
Linux Intel machine, I get

h8300-hms-gcc -g -O2  -O2 -DSMALL_DTOA -DSMALL_MEMORY -fno-builtin
-I/home/jethro/h8300-hms-build/newlib-build/h8300-hms/newlib/./targ-include
-I/home/jethro/h8300-hms-build/newlib-1.8.0/newlib/./libc/include -c
../../../../../newlib-1.8.0/newlib/libm/math/ef_hypot.c
h8300-hms-gcc: Internal compiler error: program cc1 got fatal signal 6

(Long lines wrapped.) Compiling the file with -O0 works.

Egcs was configured with

configure --prefix /home/jethro/h8300-hms --target h8300-hms --enable-haifa
--with-newlib

and compiled with (gcc -v):
Reading specs from /usr/lib/gcc-lib/i386-linux/2.7.2.1/specs
gcc version 2.7.2.1

h8300-hms-gcc -v gives:

Reading specs from
/home/jethro/h8300-hms/lib/gcc-lib/h8300-hms/egcs-2.90.25/specs
gcc version egcs-2.90.25 980302 (egcs-1.0.2 prerelease)

Included below is the problem file, produced with h8300-hms-gcc -E ... >file.
