Bug ID: 45476
Summary: _Atomic struct can hang compiler
Product: new-bugs
Version: 9.0
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: vtjn...@gmail.com
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org
Running this:
```
$ clang-9 -x c++ -S - -std=c++11
typedef signed char int8_t;
struct i8_3 {
int8_t a;
int8_t b;
int8_t c;
};
_Atomic struct i8_3 a;
void jwn1() {
a = i8_3{1, 2, 3};
}
int8_t jwn2() {
return a.a + a.b + a.c;
}
```
The compile never finishes. Possibly similar to #14442?
