Frank Lichtenheld reported the following bug in gcc from trunk while compiling
the Linux kernel:

tbm@meitner:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O mxb.i
drivers/media/video/mxb.c: In function 'mxb_ioctl':
drivers/media/video/mxb.c:925: error: unrecognizable insn:
(insn 148 147 149 30 drivers/media/video/mxb.c:545 (parallel [
            (set (mem/s:QI (reg:SI 215) [0 S1 A32])
                (const_int 0 [0x0]))
            (clobber (reg:SI 216))
            (clobber (reg:SI 217))

            (use (const_int 4 [0x4]))
        ]) -1 (nil))
drivers/media/video/mxb.c:925: internal compiler error: in extract_insn, at

Please submit a full bug report,
with preprocessed source if appropriate.

This happens at least with GCC from trunk from 20070829 and 20070902.
