Hi Croco,

What Owl kernel version do you have on that host ("uname -rm", please)?

This is news to me, and I can't reproduce it.  For example, taking our
crypt_blowfish 1.3 and running "make check_threads" in a 32-bit Owl
container on a 64-bit Owl host works just fine for me.  Can you also try
this very test?
