Interesting:

  Extended opcode 2: set Address to 0x0
  Advance Line by 30 to 31
  Copy
  Special opcode 63: advance Address by 4 to 0x4 and Line by 2 to 33
  Advance PC by 2 to 0x6
  Extended opcode 1: End of Sequence

GCC has done this for as long as I remebmer; your version has leaveq
associated with the open brace, which is clearly strange.  I can
reproduce that with GCC 3.3 and 3.4, so you're right; it must be fixed
in 4.x.

Anyway, now we see how to fix the testcase :-) I'm pretty sure an
actual function body won't affect what they're testing for.  Does
this help?
