Just a few comments
I suspect this error is more subtle than just your 23-4 changes, Guenter, because of the loss of fuctionality at 23-1.
I have MIDI functionality in version 23-2 but not in 23-3 (as I have notified Guenter earlier)
Your changes may just have exposed where RedHat OSS fails with new 0.23 scheme.
I am not sure, that RedHat is the problem... It works fine to me, if I use OSS and NOT ALSA drivers.
