Yes, I have looked at this application.
It loads fine under Windows - however, both dependancy walker and the
Nt quick viewer are not happy with it (one displays that there is a format
error in the exe, the other loops and finally crashes)
 
The web site says that this executable is compressed with a tool called UPX.
This
seems to be the reason for the problem, as the original program is compiled with
Ms VC++ - not a very exotic tool.

I think that a fix could be to detect a corrupted header in dump_exports and
to not try to display anything if numberoffunctions is not coherent with the
export
section size.

I tried a hack for that and virtualdub got further; however, I see that it is
trying to load avicap32.dll and this is not going to work - even under Linux
;:-)
