Really, in my posts, I never cited 'glxgears', 'glxinfo' etc.
Sincerely, I do not know what they are...

I have written:

1. Adding +bs at command line which starts XWin (in startxwin.bat) and
then trying to run some ROOT macro (hsimple.C etc.) both ROOT and
XWin-1.5.3-4 (from [1]) segfault. Using YOUR XWin with debug info etc.,
ROOT, hsimple.C etc. work fine, i.e. NO segfault etc.

2. Adding +bs at command line which starts XWin (in startxwin.bat) and
then trying to run some ROOT OPENGL macro (geom/shapes.C, for example
see [2]) then the macro fails to be excuted (see [2]), but it works if I
omit '+bs' OR if I use the workaround described here [3] OR if I use
YOUR debug XWin.exe!

MAY YOU try [1] with the steps described in [2] and confir/or not the
segfaults?


Cheers,
   Angelo.
