I'll open a feature request for more reliable segfaults. ;)
Still, on FreeBSD-8.0 the patch does not produce a traceback and also
appears to change the signal:
[without the patch]
$ ./python Lib/test/crashers/compiler_recursion.py
Segmentation fault: 11 (core dumped)
$ echo $?
139
[with the patch]
$ ./python Lib/test/crashers/compiler_recursion.py
Illegal instruction: 4 (core dumped)
$ echo $?
132
