[Bug c++/31759] New: [4.3 regression] ICE with OpenMP and exceptions

[reichelt at gcc dot gnu dot org]

The following testcase (similar to PR26913) triggers an ICE on mainline:

=============================
struct A
{
    ~A() throw();
};

void foo(A);

void bar()
{
#pragma omp parallel
    {
        A a;
        foo(a);
    }
}
=============================

bug.cc: In function 'void _Z3barv.omp_fn.0(void*)':
bug.cc:10: error: unnecessary EH edge 5->6
bug.cc:10: internal compiler error: verify_flow_info failed
Please submit a full bug report, [etc.]

It's a recent regression since the code compiled without problems last week.
