Mitchell Horne <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Mitchell Horne <[email protected]> --- (In reply to John F. Carr from comment #0) Hi, thanks for the report. I have a couple of questions. First, how easily is this crash reproduced? Does it trigger consistently every time, after the program has run a while, or very rarely? What is the threading model of the program? Does it consist of several long-lived threads or does it continuously spawn many threads with short lifespans? If you are able to share the referenced program, or another reproducer, that would go a long way to assist with isolating the issue. My guess as to how this assertion could occur is that one of the relevant fields in the thread are not being cleared/initialized properly, and re-use of the thread structure results in an unintended call to pmc_capture_user_callchain(). -- You are receiving this mail because: You are the assignee for the bug.
