[Bug c/35893] New: ice for legal code

[dcb314 at hotmail dot com]

I just tried to compile the Suse Linux package smalltalk-2.1.12
with the GNU C compiler version 4.4 snapshot 20080404

The compiler said

 gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -I../lib-src -I../lightning
-I../lightning -I../snprintfv -I../snprintfv
-DKERNEL_PATH=\"/usr/share/smalltalk/kernel\" -Wall
-DIMAGE_PATH=\"/usr/share/smalltalk\" -DMODULE_PATH=\"/usr/lib64/smalltalk\"
-O2 -g -fmessage-length=0 -D_FORTIFY_SOURCE=2 -Wall
-Wdeclaration-after-statement -Wno-format -Wno-parentheses -Wpointer-arith
-Wno-pointer-sign -Wno-strict-aliasing -Wno-switch -fno-gcse
-fno-strict-aliasing -MT oop.lo -MD -MP -MF .deps/oop.Tpo -c oop.c -o oop.o
oop.c: In function '_gst_mark_an_oop_internal':
oop.c:2060: 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 -Wall required

Here is some additional help from valgrind
