Summary: ICE in tsubst_omp_clauses, at cp/pt.c:17520
Product: gcc
Version: 12.0
Status: UNCONFIRMED

g++-12.0.0-alpha20210530 snapshot (g:a0a7adeea31918deefb053a9a15257af94aecfaf)
ICEs when compiling the following testcase, reduced from
test/OpenMP/task_ast_print.cpp from the clang 12.0.0 test suite, w/ -fopenmp:
struct S1 {
S1 () {}
};
template <typename T>
class S7 {
protected:
T c[10];
public:
S7 () {
#pragma omp task affinity (iterator (i = 0 : 10 : 1): c[i])
for (int k = 0; k < 1; ++k)
;
}
};
struct S8 : public S7<S1> {
S8 () : S7<S1> () {}
};
% g++-12.0.0 -fopenmp -c jhbrjcts.cpp
jhbrjcts.cpp: In instantiation of 'S7<T>::S7() [with T = S1]':
