[Bug target/33138] New: [4.3 Regression] rejects valid? assembler, segfaults

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

There are two issues here:
 - the inline assembly is rejected at -O.  I don't know if the assembler
   code is valid, but fwiw it's accepted by gcc 4.1 and 4.2.
 - gcc segfaults.

I see this with current trunk and with trunk from 20070720.
