[Bug c++/27315] New: ICE with ill-placed #pragma omp parallel

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE when compiled with -fopenmp:

===================================
struct A
#pragma omp parallel
{
    template<int> void foo();
};

template void A::foo<0>();
===================================

bug.cc:2: error: '#pragma' is not allowed here
bug.cc:7: error: invalid use of incomplete type 'struct A'
bug.cc:1: error: forward declaration of 'struct A'
bug.cc:7: internal compiler error: tree check: expected tree that contains
'decl common' structure, have 'error_mark'  in do_decl_instantiation, at
cp/pt.c:11209
Please submit a full bug report, [etc.]
