--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed. Reduced test-case:
$ cat pr96315.c
int main_njack;
void main() {
struct {
double aic[main_njack];
} res;
#pragma omp parallel
for (;;)
res;
}
$ gcc pr96315.c -c -O1 -fopenmp
during GIMPLE pass: omplower
pr96315.c: In function \u2018main\u2019:
pr96315.c:6:9: internal compiler error: tree check: expected tree that contains
\u2018decl minimal\u2019 structure, have \u2018error_mark\u2019 in
remap_type_1, at tree-inline.c:586
