I got it both on my laptop and desktop, identified as core2 and coreinhm, 
hydra also gets the same error, and even tom for a machine you have 
access to.

By the way, on shell, gcc -m32 simply fails for me with:
/usr/bin/ld: skipping incompatible /usr/lib/libgcc.a when searching for -lgcc
(I know there is a /usr/lib32, but it doesn't seem to look there by 
default)
