[lno] ICE in tree-ssa-loop-ivopts.c:545

[Richard Guenther <rguenth at tat dot physik dot uni-tuebingen dot de>]

Hi!

I just decided to give lno a try and experience the following ICE
compiling the testcase at
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/tramp3d-v2.cpp.gz
with -O2 -ftree-loop-optimize on ia32 linux:

GNU C++ version 3.5-tree-ssa-lno 20040210 (merged 20040120)
(i686-pc-linux-gnu)
        compiled by GNU C version 3.3.3 20040201 (prerelease).
GGC heuristics: --param ggc-min-expand=98 --param ggc-min-heapsize=129002

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Is this expected? I.e. is lno suitable for testing already?

Thanks,
Richard.
