Uninitialized value warning from valgrind: VBoxGuestAdditions-4.1.22/lib/VBoxOGLcrutil.so)

[ci-zephyurus]

When I tried to run thunderbird (mozilla mailer which was compiled and linked locally) under valgrind I got a warning about uninitialised value usage in VBoxOGLcrutil.so.

It would be nice if someone can look into which value is not initialized.

It seems to me that a local variable or part of it (on the stack) is used without proper initialization.
