The internal compiler bug on legal code similar to bug 15342.
This bug manifest itself on specific combination of two functions
accessing structure fields and containing more return paths.
If one of the functions is moved into separate file, error seems
to disappear.

arm-linux-gcc --pipe -B/opt/rtems/arm-rtems/csb336/lib/  \
-mcpu=arm920 -mstructure-size-boundary=8 -msoft-float \
-g -Wall  -O3 -g \
-o icetest1.o \
-c icetest1.c

icetest1.c: In function `sui_get_event':
icetest1.c:172: internal compiler error: in verify_local_live_at_start, at
flow.c:546
Please submit a full bug report,
with preprocessed source if appropriate.

Experienced on next x86 to ARM GCC builds

GCC 3.4.1 and GCC 3.4.2
./configure --target=arm-rtems --prefix=/usr --with-cpu=arm9 \
  --enable-languages=c,c++ --with-gnu-ld --with-float=soft \
  --enable-threads=rtems --enable-target-optspace --verbose  \
  --disable-nls --host=i586-pc-linux-gnu --with-newlib
Thread model: rtems
gcc version 3.4.2

GCC 3.4.1
./configure --target=arm-linux --prefix=/usr --with-cpu=arm9 \
--enable-languages=c,c++ --with-gnu-ld --enable-shared --enable-symvers=gnu \
--with-float=soft --enable-threads=posix --enable-__cxa_atexit \
--enable-target-optspace --verbose --disable-nls --host=i586-pc-linux-gnu \
--with-headers=/usr/src/linux-2.6.8-rc1-arm/include
Thread model: posix
gcc version 3.4.1

Attached reprocessed sources length reduced form original 3150 lines
to 173 lines. More attempt to simplify code even more lead to compilation
without errors.
