Client: Windows  
Gateway: RHEL  
Server: RHEL  
Version: 5.11.2 (official binaries)

Launch client and set to listen for reverse connection  
pseudocode:  
ssh -R 11111:localhost:port gateway  
ssh -R port:localhost:11111 server /bin/pvserver -r

This works as intended when using osmesa on the back end. (Same commands; swap -egl- for -osmesa- in the path) Using egl, it segfaults in libc inside the vtkEGLRenderWindow::SetDeviceAsDisplay() call.

Can anyone give me some ideas of how to start debugging this?
