Here's a smaller testcase:
tbm@meitner:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O mxb.c
mxb.c: In function 'mxb_probe':
mxb.c:30: error: unrecognizable insn:
(insn 10 9 11 3 mxb.c:29 (parallel [
(set (mem/s/j/c:QI (reg:SI 98) [0 D.1580.name+8 S1 A64])
(const_int 0 [0x0]))
(clobber (reg:SI 99))
(clobber (reg:SI 100))

]) -1 (nil))
