[Bug tree-optimization/29879] New: [Regression] ICE: verify_flow_info: loop_father but no loops

[burnus at gcc dot gnu dot org]

The following program gives with current gcc SVN 4.3.0 20061117 an ICE when
compiled with "-O2 -funroll-loops":

ice.c: In function 'main':
ice.c:14: error: verify_flow_info: Block 2 has loop_father, but there are no
loops
ice.c:14: internal compiler error: verify_flow_info failed

The same options work with gcc 4.2.0 20061117.

typedef struct mytype
{
  int i;
}
mytype;

int main ()
{
  int i8;
  struct mytype y;
  y.i = 2;
  i8 = 8;
  return 0;
}
