[Bug tree-optimization/33361] ICE in find_outermost_region_in_block, at tree-cfg.c:4803

["gcc at abeckmann dot de" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from gcc at abeckmann dot de  2007-09-09 12:51 -------

testcase (reduced to be < 500k)

Sorry for the delay of the testcase, I had to reduce it from 1.9 MB to 440 KB.
(Is there some helper script that can do this in a more or less brute force
way?
Strip complete namespaces, classes, member functions, ... from the code,
recompile and check for a certain error message? Continue it it's still there
and backtrack otherwise?)
