Bug ID: 103119
Summary: ICE in get_imports, at gimple-range-gori.cc:230
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: vsevolod.livinskij at frtk dot ru
Target Milestone: ---
The bug is not reproducible on the trunk anymore (the reduction process took
forever).
I don't know if it was fixed or became latent. Feel free to close it if it is
not relevant anymore.
Reproducer:
unsigned short a;
bool b;
int h, f;
extern bool d[][1];
char g;
void i() {
for (short c = 0; c < 10; c += 3)
for (unsigned e = 0; e < a; e = (d[c][0] ? true : 5) * (6021496ULL * b) ?:
f)
h = g;
}
Error:
