SYMPTOMS
During high levels of computer stress, a pointer move/assignment may be overwritten by another thread before that pointer is used by the owning thread. When the pointer becomes invalid, you may receive the following error message on a blue screen:

Stop 00000050 (0xa8070f7c, 0x00000000, 0x00000000, 0x00000001)



CAUSE
The failure actually occurs in nt!ObSetSecurityDescriptorInfo because of a pointer move not being under a lock.
