Hi,

I'm getting an
    internal compiler error: in find_outermost_region_in_block, at 
    tree-cfg.c:4803
in -fopenmp mode with g++ 4.2.[012]. g++ 4.3 produces no error.

Andreas

------- Comment #1 from gcc at abeckmann dot de  2007-09-09 12:51 -------
Created an attachment (id=14177)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14177&action=view)
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?)
