>Description:

gcc crashes on the following (invalid) input:

$ g++ -c x2.cc
x2.cc: In function `void foo(int)':
x2.cc:7: error: variable `C x' has initializer but incomplete type
x2.cc:9: internal compiler error: tree check: expected class 't', have 'x' (
   error_mark) in decl_jump_unsafe, at cp/decl.c:4838
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

>How-To-Repeat:

---------------------------------------------------
class C;

void foo (int c)
{
  switch (c) {
  case 0:
    C x = 1;
    break;
  default:
    break;
  }
}
