My bad, I used wrong tree... The problem is in these patches:
http://gcc.gnu.org/ml/gcc-patches/2004-12/msg01381.html and not in mainline.

Why did you mark this bug as a duplicate?
Because all these bugs (18542, 18563, 18564) triggered on one testcase and have
identical backtrace.

N is number of nested loops.
