Dear Max,

Thanks, that's even better than the large program!

When I run that program on my machine (also a 64-bit system that
seems to use the same version of the X11 library) I don't get a
segmentation fault. And the output of valgrind also shows some
informations about some memory blocks allocated by X11 and not
deallocated before the program exists...

One thing that comes to mind is that there could be a conflict
between header files, i.e. different versions of <forms.h>, being
installed and the wrong one for the version of the library you're
using getting picked up. Could you check if there's more than one
header file named forms.h installed on your machine in the paths
in which the compilers looks for header files?

If that's not the case, can you tell me which version of the 
library you're using? I, of course, test with the newest one,
so I would miss something broken in older versions...

                                Best regards, Jens
