There are more SSE4.2 instruction which allow an unaligned memory operand:
* pcmpistri
* pcmpistrm
* pcmpestri
* pcmpestrm
* crc32
(and maybe others?)
Did you catch them all?

The gcc_assert which fails is in i386.c line 10897 (latest SVN):
/* Stack align doesn't work with eh_return. */
gcc_assert (!stack_realign_drap);
