I just tried to compile the Suse Linux package qemacs-0.3.1-380.42
with the GNU gcc version 4.5 snapshot 20090528.
The compiler said
gcc: Internal error: Segmentation fault (program cc1)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flag -O3 required.
Here is some valgrind output which might help
