Bug Description

When I run this:

convert joint/* \
    -limit memory 512MiB \
 -type Grayscale \
    -crop 2x1@ +adjoin \
    -set filename:fn '%t-%[fx:1+(p&1)].%e' \
    +repage \
    'separate/%[filename:fn]'

Sometimes the "p" in the fx call doesn't update properly, leading to files getting inconsistently overwritten, like this (output from 'verbose'):

So from my interpretation, v6 is "will not fix" and v7 is "fix committed"?
