I wasn't able to reproduce this at x86_64-linux-gnu with -m32.
Tested revisions:
r163723 - crash
20100821 - crash
20100814 - crash
----- testcase.c -----
typedef char v16qi __attribute__ ((__vector_size__ (16)));
static const v16qi search = { '\n', '\r', '?', '\\' };
----------------------
(reduced from libcpp/lex.c)
The crash goes away when I add -msse2 or -msse4 or when I remove -msse.
