Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Seen with 4.1.0 i386 (with the set of patches at
http://david.woodhou.se/combine/gcc-patches since otherwise it dies a lot
earlier) and also with Red Hat's 4.1.1 branch with same patches, for i386 and
PowerPC. The attached preprocessed source will be i386.

Sorry, I'm not sure how to cut the test case down to something smaller.

Subject: Re:  internal compiler error: in cgraph_estimate_size_after_inlining,

The bug re-appeared due to yet another reorganization of IPA pass queue.
The issues with function changing their types are quite ugly, I am
looking into that now.
