aehm, triggers on ppc-linux as well. Important key: --enable-java-awt=xlib

Otherwise it does not trigger on a default config for libjava.

Have you tried configuring with --enable-java-awt="xlib"?  Otherwise,
it works for me with suse 11.0.

Segmentation fault

All the blocks we have marked in the bitmap to eh cleanup exist when
we pass them to tree_purge_dead_eh_edges.
tree_purge_dead_eh_edges seems to decide to delete some of them
earlier than it expects, and then crashes when they don't later exist.

Fyi, this seems resloved on the tuples branch. Tested on various darwin
combinations and on i686-linux.

I can reproduce this on the trunk after the tuples merge (i686).

Ok, to clarify, the bootstrap issue 'has gone', but the reduced test case from
#17 still fails. Failure confirmed on i686-apple-darwin r138861.

Created an attachment (id=16191)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16191&action=view)
gcc44-pr36766.patch

I don't see tree-ssa-dom.c or tree-ssa-pre.c are at fault here (not guessing
that some basic block will be purged as unneeded), so it should be
gimple_purge_all_eh_edges that needs to be changed to handle this.
