commit 98156e90e1e83133a6a6a020db8e7333ada6156b
Author: Steffan Karger <steffan@karger.me>
Date: Tue Dec 2 21:42:00 2014 +0100
Really fix '--cipher none' regression
... by not incorrectly hinting to the compiler the function argument of
cipher_kt_mode_{cbc,ofb_cfb}() is nonnull, since that no longer is the
case.
Verified the fix on Debian Wheezy, one of the platforms the reporter in
trac #473 mentions with a compiler that would optimize out the required
checks.
Also add a testcase for --cipher none to t_lpback, to prevent further
regressions.
