int AS m;
int *foo(void)
{
return (int *)&m;
}
```
crashes when compiled with ```clang -O2 -S``` with the following backtrace:
```

********************
PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT:
Preprocessed source(s) and associated run script(s) are located at:

```
If the testcase is changed to:
```
#define AS __attribute__((address_space(3)))
int AS m;
int *foo(void)
{
return (int *)(unsigned long)&m;
}
```
then the compilation succeeds without problems.
