Yeah, I just ran into what looks like the same bug myself. It seems it
is in magnum-jumbo only. Please try to downgrade to 1.7.9-jumbo-6
release. (And we'll fix the bug in magnum-jumbo indeed.)
Dhiru - on Linux, magnum-jumbo fails with Alex's keychain as follows:
Warning: detected hash type "keychain", but the string is also recognized as "keychain-opencl"
Use the "--format=keychain-opencl" option to force loading these as that type instead

This is a linux-x86-64-gpu build invoked with no options. With
--format=keychain-opencl, this same build works just fine:
$ ./john pw-keychain -fo=keychain-opencl -pla=1

So looks like you introduced a bug into the CPU code sometime after jumbo-6.
