[PD] Pd-0.39-2 segmentation fault

[Gerda Strobl]

Dear all,

I am using Pd version 0.39-2 on linux debian.

I wanted to produce using the makefilename object a symbol that contains 
a number and a symbol (123test.mtx), by giving the makefilename the 
wrong %%order my whole pd crashed immediately, producing a segmentation 
fault.
attached is the test patch with explanations.
