Bug ID: 111821
Summary: GCC: 14: continue to consume memory until OOM
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:
```
typedef union { char a[1003263430]; }
__attribute__((__packed__)) T;
void f(const void *p) {
unsigned short v;
*(T *)(void *)(&v) = *(const T *)p;
}
```
When compile it with `gcc -Og`, gcc used up 8GB of memory on my computer, but
when compile with other options like `-Os`, it normally returns.
