Bug ID: 58874
Summary: [4.9 Regression] [c++11] ICE with OpenMP reduction
declaration and -std=c++11
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid code snippet triggers an ICE on trunk if compiled with
"-fopenmp -std=c++11"):
==========================================================================
struct A
{
template<int> struct B
{
#pragma omp declare reduction (x : int : omp_out |= omp_in)
};
};
#pragma omp declare reduction (x : int : omp_out |= omp_in) initializer
(omp_priv = 0)
==========================================================================
bug.cc: In function 'void omp declare reduction x~i(int&)':
bug.cc:13:85: sorry, unimplemented: unexpected AST of kind decl_expr
#pragma omp declare reduction (x : int : omp_out |= omp_in) initializer
(omp_priv = 0)

Please submit a full bug report, [etc.]
The code compiles fine without "-std=c++11".
The regression was introduced between 4.9.0 20131005 and 4.9.0 20131012.
