--- Comment #3 from David Binderman <dcb314 at hotmail dot com> ---
From a valgrind run:

==4110530== Use of uninitialised value of size 8
==4110530==    at 0x401145: crc32_byte (csmith.h:73)
==4110530==    by 0x401167: crc32_8bytes (csmith.h:99)
==4110530==    by 0x401167: transparent_crc (csmith.h:112)
==4110530==    by 0x401640: main (in.18229.c:890)

I should have thought of valgrind earlier. Sorry.
