Public bug reported: A new fix has been merged into the libglvnd repo at https://gitlab.freedesktop.org/glvnd/libglvnd
This change fixes an issue where if eglReleaseThread gets externally called after the EGL destructor, a double free occurs due to the threadState that eglReleaseThread checks is not null being not null despite being freed by the destuctor. The change makes the threadState null in the destructor to fix this. Can this make it into the libs in 20.04 LTS?
