ICEs when compiling the following testcase, reduced from
test/OpenMP/depobj_ast_print.cpp from the clang 11.0.0 test suite, w/ -fopenmp:
void
dh (int *vp, int pm, int ca)
{
#pragma omp depobj (pm) depend (iterator (ca = 0 : *vp), in: vp[ca])
;
}
% g++-11.0.0 -fopenmp -c wmttbiko.cpp
wmttbiko.cpp: In function 'void dh(int*, int, int)':
wmttbiko.cpp:4:65: internal compiler error: in cp_parser_omp_var_list_no_open,
