[Bug tree-optimization/39394] [4.4 regression] ICE in copy_tree_body_r

[falk at debian dot org]

------- Comment #5 from falk at debian dot org  2009-03-09 10:59 -------
Here's a test case:

void *p;
extern inline void *f1(int n) {
    asm volatile("" : "=m"(*(struct { char x[n]; }*) p));
}

int x;
extern inline void f2() {
    x ? f1(1) : f1(2);
}

inline void f3() { f2(); }
void f4() { f3(); }

With trunk #144708, I'm getting:

min.c: In function 'f4':
min.c:12: internal compiler error: in copy_tree_body_r, at tree-inline.c:1042
