Bus error on sparc64

[GoogleCodeExporter]

Hi,
I'm testing redis on OpenBSD-current. While the testsuite successfully runs on 
i386 (all tests passed), redis crashes with a sigbus error on sparc64 during 
test #24 (SETNX will overwrite EXPIREing key). This is the gdb output:

I suspect this is caused by sparc64 strict alignment requirements, but I'm not 
particularly skilled in this area...

Hello! in order to solve this I need shell access to such a box. Please can you 
provide me with an access?

Thanks,

After your last commit, now redis passes all the tests on OpenBSD/sparc64.

Thank you,
