Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

Incomplete. Unfortunately crashing inside malloc means the process heap had already become corrupt some time before the crash happened. So we are unable to debug the origin of the heap corruption here without exact detailed steps to reproduce the problem.
