Re: X problems in Slink

Hi, Jim

just tried your routine on my debian potato system and looks like it works:

before toplevel2 0 
after toplevel2 134544432 
after form

and some window appears, no segfaults

lesstif 0.88.1
egcs    1.1.2
mesa 3.0

OK


   Hi,

   I've been having problems with my system, It's a long story
   bugut to make it short I have a new mother board and have installed
   Slink on a freshly partioned drive. Every thing I've tested so far works
   except my routines that use Lesstif. I stripped the code to a minimun to
   demostrate the problem, compiled and run it on a Dec Alpha to verify it
   runs correctly, or at least OK. But on my Machine ( a K6=3 400, 256M of memory)
   it segfaults. 

   Here are the details ( sorry for the length, I wanted to include enough
   so you can see what is happening)
