Bug ID: 82835
Summary: [8 Regression] ICE on valid code with -fopenmp
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: openmp
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: jakub at gcc dot gnu.org, jason at gcc dot gnu.org
Target Milestone: ---
Starting from r251422, we ICE on:
$ cat ice7.ii
int a, b;
template <class> class c {
public:
c(int = a);
};
class d {
void e();
struct {
int g;
} chtrellis;
};
void d::e() {
c<int> f;
#pragma omp for private(f)
for (b = 0; b < chtrellis.g; b++)
;
}
$ g++ ice7.ii -fopenmp -c
during GIMPLE pass: omplower
ice7.ii: In member function ‘void d::e()’:
ice7.ii:14:9: internal compiler error: Segmentation fault
#pragma omp for private(f)
