Bug ID: 115646
Summary: [gcc][trunk] ICE in gen_conditions_for_pow_int_base,
at tree-call-cdce.cc:587
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: 141242068 at smail dot nju.edu.cn
Target Milestone: ---
Compiler explorer: https://gcc.godbolt.org/z/rax1zezbc
The testing program:
```
#include <math.h>
struct S {
unsigned int a : 3, b : 8, c : 21;
};
void foo (struct S *p)
{
pow(p->c, 42);
}
```
When compiling it using gcc-trunk with option `-O2`, gcc crashes:
```
during GIMPLE pass: cdce
<source>: In function 'foo':
<source>:7:6: internal compiler error: in gen_conditions_for_pow_int_base, at
tree-call-cdce.cc:587
7 | void foo (struct S *p)
| ^~~
0x23be10c internal_error(char const*, ...)
???:0
0x986355 fancy_abort(char const*, int, char const*)
???:0
Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
