I cannot reproduce this on powerpc-darwin but that does not mean it is not still a bug.

I cannot rreproduce this with a cross to x86_64-linux-gnu from powerpc-darwin so this is either 
wrong-code produced by the bootstrapping or a GC problem.

I see the ICE only on i586 and x86_64.  ia64 and ppc compile this file fine. 
 
Do you want preprocessed i586 code?

Preprocessed source file - i386 compilation

On i586 I get the same ICE - here's the preprocessed source file.  Hope this
helps.

Here's a reduced testcase:

===========================
int foo()
{
    unsigned char c;
    switch ((int)c)
    {
      case -1:
      case 0:
      case 4:
      case 5:
      case 42:
        return 0;
    }
}
===========================

parse.i: In function 'foo':
parse.i:13: internal compiler error: tree check: expected function_decl, have
error_mark in c_expand_body, at /c-decl.c:6334
Please submit a full bug report, [etc.]

If I replace the 42 with 39 for example, I get a segfault instead.

This might be related to PR 17657.

Note that I can reproduce it with a full bootstrap compiler but not with just stage 1 so something is 
causing wrong code somewhere.
