_XmStringIsCurrentCharset(XmStringCharset c) calling strcmp() at this point of the program it is crashing with Segmentetion fault.

I am using Windows-XP, SFU Interix and Motif library from Interop.

The default font file is set to 7x13bold.pcf,
but in the \X11R6\lib\X11\fonts\misc directory there is no such file. Now the closest to that file is: 7x13B.pcf.

There seems to be some changes between old and new Motif library. My question is How competible are they?
