[Bug tree-optimization/22329] New: VRP produces missed matched (non compatible) types in MODIFY_EXPR

[pinskia at gcc dot gnu dot org]

Take the following code:

int f(int i)
{
  int k = 0;
  if (i == 0)
    k = i == 0;
  return k;
}

(reduced from c-parser.c)
VRP produces a missed matched types in the assignment of k:
t.c: In function 'f':
t.c:2: error: statement types mismatch
kD.1266_6 = 1;

intD.0
_BoolD.1063
