I have a problem with FreeSWITCH (r13175) when using REFER. If running inside Visual Studio, everytime (during the REFER) I get a "...has triggered a breakpoint". It's possible to click continue to go on, but eventually (another 2-3 calls) FreeSWITCH crasches completely. When running outside Visual Studio I get a crasch after maybe 10 calls. Another interesting scenario is when running outside the debugger and I enable siptracing it's much more stable - even though it crasches eventually - this is what makes me wonder about mutexes... I've tracked it down to calls to malloc() and calloc() which in 100% of the cases is in the top of the call stack. My thought is that it might be related to a mutex issue somewhere. Below I've copied the call stack from two times it's happened to me. These are the most common traces, but sometimes it's a malloc being called from the sqlite lib. But so far I always think it's been related to a malloc/calloc. These things have occured in a couple of other places as well, for instance when a SIP registration fails (registering to an external server) with error 404 I also get a breakpoint triggered, but I don't think that has caused any crasches yet. I've tried to debug this on my own, but so far I didn't find anything, so that's why I'm asking you guys :) I think I'm going to try the same on Linux as well, and see if it works differently there. If you need more info, please let me know, I'll try to help out as much as possible. I thought I'd post this here first, if you have any ideas. If not I'll file a Jira for the issue. ----- ntdll.dll!DbgBreakPoint() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] ntdll.dll!RtlpNtMakeTemporaryKey() + 0x3eee bytes ntdll.dll!RtlTimeToElapsedTimeFields() + 0xd8c3 bytes ntdll.dll!RtlTryEnterCriticalSection() + 0x66f bytes ntdll.dll!RtlpNtMakeTemporaryKey() + 0x4785 bytes ntdll.dll!RtlTimeToElapsedTimeFields() + 0xd6f1 bytes ntdll.dll!RtlTryEnterCriticalSection() + 0x66f bytes
