[PD] pd crashes when using expr

[Shahrokh Yadegari]

Tina,

Yes, it seems that this a bug in expr object due to a boundary condition.
Expr was written to handle 10 expressions, and print a warning if more
expressions were supplied, but the code can only handle 8 expressions right
now. I am not setup to compile for windows. If you (or anybody else who may
have run into this problem and needs a fixed version) can compile for
windows, I can send you corrected source files, otherwise I suggest that you
edit your file with an editor and drop one of the expressions from the expr
list (the first one? which is only passing the first inlet).

I will fix this shortly and put out a new version (for linux and darwin) on
my website.

cheers,
Shahrokh.
