Hello,

I have recently installed Pymol 1.7.6 (also tested with 1.7.4 and 1.6.0)
using gcc 4.8.3-9 on CentOS 7. The operating system is installed in VMware
workstation 10.0.5 with hardware acceleration enabled. I installed the
scripts and modules in an independent directory as described here:
http://www.pymolwiki.org/index.php/Linux_Install

Pymol starts up and appears to run fine, but anytime I quit or load any XYZ
file, the program quits unexpedidly and claims there is a segmentation
fault. The "Representations" demo also causes the problem. I am uncertain
where to get further details to pinpoint the library causing the fault, but
I would like some advice to see if there is anything I can do to correct
the problem. I attempted mono and many of the commandline options, but
nothing is helping.

Interestingly, I ran the pymol benchmark tool from the commandline, which
does not cause a segfault. In fact, after opening pymol using the `-b`
flag, I can then load any XYZ file without segfault. However, the view
keeps blinking during movement. It may also be of interest to note that I
have used opencascade without any problems as a 3d rendering and cad
visualization software on this same VM.

Thank you,
Derek Thomas
