Sorry, process substitution works. I did something stupid with dd. The only problem is 0 length input:
./rados --pool=test put --striper $RANDOM <(dd if=/dev/urandom count=0 bs=0)
Result: crash

This bug seems to be fixed in master. I'm now trying to find out when it's fixed then back it port to older version(jewel, infernalis(, hammer?))
@Shinobu: Please note that infernalis has already been retired. We will still backport bugfixes to hammer until the luminous release, but the focus there is on fixing bugs (if any) that prevent users from upgrading to jewel. Knowing that, if you still want to submit a hammer backport for review you are welcome to do so.
