Is it pointed out anywhere that this fix _induces_ segmentation
faults in Performer 1.2 code? I can't find any reference to this
in the release notes. Has anyone else found that their freshly
ported Performer 1.1 apps crash ingloriously?

Perhaps the
        '/usr/src/Performer/src/tools/port1.2'
conversion script should flag this situation with a comment somewhere
in the neighbourhood of pfNewChan() calls.

Cheers,
Jean Daigle.
