[Bug c/30244] New: ice for legal code with -O2

[dcb314 at hotmail dot com]

I just tried to compile the attached code with
the snapshot 4.3-20061216 C compiler.

The compiler said

dcb@linux:~/gnu/20061216/bugs> ~/gnu/20061216/results/bin/gcc -c -O2 bug27.c
bug27.c: In function 'conf':
bug27.c:4452: internal compiler error: in insert_into_preds_of_block, at
tree-ssa-pre.c:2750
Please submit a full bug report,
with preprocessed source if appropriate.
