[Bug c++/38648] New: [4.2/4.3/4.4 regression] ICE with string literal

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

========================
char a[1];

int foo(
{
  a = "";
  return 0;
}
========================

bug.cc:5: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

A similar code snippet triggers an ICE since GCC 3.1:

========================
char a[1];

int foo(a = "")
{
  return 0;
}
========================

bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
