OpenGL Sync object regression in Catalyst 13.9

    I have a AMD radeon HD 7770 video card, Today I upgrade video driver to Catalyst 13.9 in my Windows 7 x64 machine.

    I have a big program which use openGL heavily, it runs fine in the past several years, but after the upgrade, it will sometimes crash in openGL function call related to Sync object. Such as glDeleteSync and glClientWaitSync. One thing I must point out is that I call sync object function in different threads, such as I create a sync object in one thread and wait it in another thread.

    Since my program is very huge, it is not possible to attach it.

    Does anybody also encounter this problem?
