------- Comment #7 from reichelt at gcc dot gnu dot org  2006-02-23 22:42 -------
The testcase in comment #3 crashes again on mainline
when compiled with "-O2 -ftree-loop-linear" at least
on i686-pc-linux-gnu and x86_64-unknown-linux-gnu.

The 4.1 branch seems not to be affected.
The testcase crashes at least since 20060211.

The testcase in comment #3 compiled with "-O2 -ftree-loop-linear"
still ICEs on x86_64-unknown-linux-gnu.

------- Comment #13 from reichelt at gcc dot gnu dot org  2007-07-07 11:07 -------
The testcase indeed doesn't crash on mainline (i686-pc-linux-gnu) anymore.
It still crashes on the 4.2 branch, though.
Given that the testcase disappeared and reappeared on mainline the problem
might
still be latent on mainline.
