------- Comment #1 from gcc at abeckmann dot de 2007-09-09 12:51 -------
Created an attachment (id=14177)

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?)

------- Comment #7 from reichelt at gcc dot gnu dot org 2007-12-27 16:03 -------
Shorter testcase that crashes already with "-O -fopenmp":
======================================
void foo();
struct A
{
A() throw() { foo(); }
};
void bar()
{
#pragma omp parallel
A a, b;
}
======================================
