Hmm - [5] accesses a member variable of the m_reqfile, but [6] just verified that the m_reqfile is not NULL.

Can you create a full backtrace ?

I'll see what I can do, this is Festor's Jaunty build.

Meantime another crash has manifested:

Another thing looking pretty much impossible.  :(
Code: [Select]
m_dwDirectCallbackTimeout = ::GetTickCount() + SEC2MS(45);
theApp->clientlist->AddDirectCallbackClient(this);
Unless it's a case of memory corruption which is pretty much impossible to track down.
