I just tried to compile a snapshot of Open Office
with the 4.5 snapshot 20091015

The compiler said

../../../js/src/jsinterp.c: In function 'js_Interpret':
../../../js/src/jsinterp.c:6226:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O required.

Here is valgrind helping out with a stack backtrace

==25608== Invalid read of size 8
==25608==    at 0x527610: bitmap_clear (bitmap.c:297)
==25608==    by 0x6D4F8D: move_loop_invariants (loop-invariant.c:1559)
==25608==  Address 0x78 is not stack'd, malloc'd or (recently) free'd
