Hi,
  Since you are running a test build of VMD 1.9.4 and there are no
NVIDIA GPUs, I believe your problem is the same as the other person
I answered earlier today, a crash caused by a bug in one of the latest
revs of NVIDIA's OptiX library. Try setting this environment variable
before running VMD and see if the crash goes away:

/bin/bash shell:
  export VMDNOOPTIX=1

/bin/csh shell:
  setenv VMDNOOPTIX 1

If that cures the crash, then it is the same as the one observed
by the other recent reporters and it will be fixed when NVIDIA
releases a new OptiX library and/or if I can develop a safe workaround
to prevent it in the interim until NVIDIA gets a new build released.

Best regards,
  John Stone
