------- Comment #3 from spop at gcc dot gnu dot org 2009-12-23 18:11 -------
The testcase fails without graphite at -O0, probably a problem in the C++
front-end:
stopping the execution randomly, I get the following backtraces:

This stops after one or two minutes, depending on stack ulimit. With
an older compiler, I get this time:
time g++-4.3 -O3 -c ~/gcc/graphite/gcc/testsuite/g++.dg/graphite/pr41305.C
real 0m0.103s
