Check for NULL extensions string
Some X server not supporting any OpenGL feature, glXQueryExtensionsString
will return NULL and causes the function to fail.
Thanks to Emmanuel Stapf (manus@eiffel.com) for the original patch.
This was verified running an application on macOS while the X server was
running on Windows Xming 7.5.0.10
