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
