This fixes an incorrect debug-mode assert: - T1 starts an arena stats update and reads stack_head from another thread's cache bin, when that cache bin has 1 item in it. - T2 allocates from that cache bin. The cache_bin's stack_head now points to a NULL pointer, since the cache bin is empty. - T1 Re-reads the cache_bin's stack_head to perform an assertion check (since it previously saw that the bin was empty, whatever stack_head points to should be non-NULL). |
