[Bug middle-end/27325] New: ICE with enabled exceptions and -fopenmp

[Georg dot Baum at post dot rwth-aachen dot de]

The code

struct A {
        ~A();
};

int f()
{
        A a;
#pragma omp parallel firstprivate(a)
        for (int i = 0; i < 5; ++i)
                int x = 0;
        return 0;
}

gives the following ICE with gcc version 4.2.0 20060426 (experimental):

LANG=C g++-4.2 -c -fopenmp  -o gcc-bug.o gcc-bug.cpp
gcc-bug.cpp: In function 'int f()':
gcc-bug.cpp:5: internal compiler error: in find_outermost_region_in_block, at
tree-cfg.c:4758

This is reduced from the same code as PR26913 (thanks for the fix). The ICE
disappears with -fno-exceptions. I am not sure whether this is a duplicate of
PR26823, but the ICE appears in a different file, so maybe it is not.

In the process of reducing I got also two other ICEs:

gcc-bug.cpp:16: internal compiler error: in make_decl_rtl, at varasm.c:1009

and

gcc-bug.cpp:27: error: basic block 5 edge lists are corrupted
gcc-bug.cpp:27: internal compiler error: verify_flow_info failed

Since these appear in a rather large file I'll reduce them further and file
reports after this problem is fixed (if they still appear then).

------- Comment #2 from Georg dot Baum at post dot rwth-aachen dot de  2006-04-28 15:05 -------
The patch at http://gcc.gnu.org/ml/gcc-patches/2006-04/msg01084.html fixes the
problem for me. Now my code compiles without optimization, but with -O1 or
higher I get a different ICE without file location that is very difficult to
reduce. I'll file a new report when I managed to reduce it to something
reasonable.
