[Freeswitch-dev] FreeSWITCH on Windows crashing when doing deflect/REFER

This one was solved a long time ago, so you probably have a completely different problem. And yes, it was a bug, which was fixed a couple of days after it was reported. I don't remember the jira ticket ID, but I don't think it will help you much more anyway...

If you think you've hit a bug, read the guidlines about how to report it on jira, and then file a new ticket.

Regards,

Peter Olsson

Ämne: Re: [Freeswitch-dev] FreeSWITCH on Windows crashing when doing deflect/REFER

Hello,

I have a simliar problem with starting thread (not with REFER), that I 
can't reproduce on linux.
Could you please tell me what was the solution for you?
Was it a bug? If yes, which jira ticket is this?

Thanks in advance,
Tamas

> 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.
