------- Comment #3 from rguenth at gcc dot gnu dot org  2009-06-24 09:42 -------
ICEs with -O -ffast-math -floop-block:

source/blender/radiosity/intern/source/radfactors.c: In function
'calcSidefactors':
source/blender/radiosity/intern/source/radfactors.c:192: error: definition in
block 4 does not dominate use in block 30
for SSA_NAME: ysq_19 in statement:
D.7069_152 = ysq_19 + 1.0e+0;
source/blender/radiosity/intern/source/radfactors.c:192: internal compiler
error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

also ICEs the same way on the trunk.
