I agree that the most likely explanation is a bug in my code as the unit tests for that section of code execute correctly. However, examini= ng the data structures using GDB between succeeding and failing calls, I have verified that the cond var and the lock memory addresses are not being modified. Visibility and access to the lock and cond vars does not escape t= he .c file so I can't see where overwriting or corruption of the lock and cond vars could happen. --=20 You are receiving this mail because: You are the assignee for the bug.=
