--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-04-05 08:48:34 UTC ---
The test case works with -fno-realloc-lhs.

Thus, it might be related to PR 48360 (there one has a segfault and no ICE).

Obviously mine.

It seems to go away with my fix for PR48360, although I will have to verify
that this weekend.
