I later got the score from Andre and located the problem. I'm writing to
the list to announce that Andre wins the Ickbug Award for 2001, given to the
finder of the most obscure bug, one that depends on the most unlikely set of
interactions. Here's an example of the prize-winning bug:
======================================
3 -2 1 2 4 4 0 6 0 -2
1 2 20 .07
Ped.
Man.
btt
./
c04 c /
c04 Ca c /
c04 c /
%
L2Mn12tt
K+0+2
c04 | Cb c /
c04 c /
======================================
In the second system, the last note in the upper staff thinks it's in alto
clef. My proposed fix will be in the next PMX release.
Oh, and the prize is naturally a free copy of PMX.
Happy Holidays!
