Bug ID: 112487
Summary: GCC: 14: internal compiler error: in
setup_one_parameter, at tree-inline.cc:3565
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/fjErPvrvP
When compile this program with `gcc-14 -O1`, gcc crashes:
```
struct A { char i; };
struct B {
struct C *p;
struct A *q;
};
struct C { struct B a[1]; };
struct T { struct U *ptr; };
volatile struct T v;
void f1(volatile struct T v) { f2(v); }
void f2(volatile struct T *const v) { }
void bar() {
struct U *ptr;
f1(v);
}
```
The crash output pasted from compiler explorer:
```
<source>: In function 'f1':
<source>:10:32: warning: implicit declaration of function 'f2'; did you mean
'f1'? [-Wimplicit-function-declaration]
