The none/tests/x86/crc32.vgtest fails when clang is used for the compilation:
$ CC=clang CXX=clang++ ./configure
...
$ tests/vg_regtest none/tests/amd64/crc32.vgtest none/tests/x86/crc32.vgtest
crc32: valgrind -q ./crc32
crc32: valgrind -q ./crc32
*** crc32 failed (stdout) ***

none/tests/x86/crc32 (stdout)
$
$ sdiff ./none/tests/x86/crc32.stdout.exp ./none/tests/x86/crc32.stdout.out |
tail -3
m crc32_u32 122de453 7ebadd80 ec581a76 00000000 | m crc32_u32
122de453 7ebadd80 ec581a76 00000084
r crc32_u32 40ad0d2c 61ae8842 180bde9b 00000000 | r crc32_u32
40ad0d2c 61ae8842 180bde9b 00000084
m crc32_u32 63f36dc9 b2ea8964 76b5456b 00000000 | m crc32_u32
63f36dc9 b2ea8964 76b5456b 00000084
$
Note how 00000000 is expected but 00000084 is actually produced.
The testcase needs update so that it works with clang too.
