------- 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.

Btw, the bug disappeared on mainline between 2007-05-13 and 2007-05-26.
