[Bug c++/27316] New: ICE with two 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 {};

struct B : A
#pragma omp parallel
{};

struct B : A
#pragma omp parallel
{};
===================================

bug.cc:4: error: '#pragma' is not allowed here
bug.cc:5: error: expected unqualified-id before '{' token
bug.cc:7: internal compiler error: in xref_basetypes, at cp/decl.c:9696
Please submit a full bug report, [etc.]

Doesn't seem to be openmp specific.
 struct A {};

 struct B : A
 !
 {};

 struct B : A
 !
 {};

ICEs the same way.

Then this is a regression since that testcase did not produce an ICE in 3.4.0.
