Bug ID: 111817
Summary: GCC: 14: internal compiler error: in expand_asm_stmt,
at cfgexpand.cc:3389
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: ---
The bug triggering program:
```
static int foo(int x, int y, int z) {
int b;
asm("" : "=a"(b), "\n=&d"(x) : "0"(y), "1"(x), "mr"(z));
return x;
}
```
The crash can be verfied at link: https://godbolt.org/z/6d7csd8xv
The full stack dump:
```
