[lno] ICE in coalesce_abnormal_edges, at tree-outof-ssa.c:645

[Richard Guenther]

With the tramp3d-v3.cpp testcase I get an ICE with todays lno branch if
compiling with -O2 -funroll-loops -ffast-math -march=athlon:

 Conflict pt_466 and pt_435 across an abnormal edge from BB17->BB19
tramp3d-v3.cpp: In member function `void
RefBlockController<T>::deleteStorage() [with T = FieldEngineBaseData<3,
double, MultiPatch<GridTag, Remote<Brick> > >]':
tramp3d-v3.cpp:10513: internal compiler error: in coalesce_abnormal_edges,
at tree-outof-ssa.c:645
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

g++ (GCC) 3.5-tree-ssa-lno 20040416 (merged 20040321)
compiler built with checking disabled.

Testcase fetchable at
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/tramp3d-v3.cpp.gz

Maybe a merge from tree-ssa would help (ICE doesn't look lno related at
first look)

Richard.
