Bug ID: 112505
Summary: GCC: 14: internal compiler error: in
build_vector_from_val, at tree.cc:2104
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

The crash triggering program (compile with `gcc-14 -O3`):
```
short int w9;
struct T {
short a : 14;
int b;
};
struct T v;
void __attribute__((simd)) zc() {
w9 *= v.b ? v.a-- < 0 : 0;
}
```
The crash output:
```
