Bug ID: 112499
Summary: GCC: 14: internal compiler error: output_operand:
invalid expression as operand
Product: gcc
Version: 14.0
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/MdacfWqhr
When attempting to compile this program with `gcc-14 -O1`, gcc crashes:
```
#include <stdint.h>
int f(void) {
static uintptr_t a = ((char *)&&l3 - (char *)&&l2) +
((char *)&&l1 - (char *)&&l2);
l1:
l2:
l3:
return a;
}
```
If removing the qualifier `static`, then this crash disappears.
The crash output:
```
<source>:10:1: internal compiler error: output_operand: invalid expression as
operand
