Re: [Quickfix-developers] FileStore crashes in .NET?

[Rick L. <ric...@gm...>]

I'm fairly certain the crash was occurring in the quickfix_net.DLL -- 
I'll repost my stack trace while debugging the .dmp file at the end of 
this email.

Is there any way the .pdb file generated when the DLL was compiled 
(sometime in 2006) can be found?  It would help me determine where in 
the quickfix code the error is occuring (right now I only have the 
address of the function).

After looking at the .dmp file and generating a new .map file for 
quickfix_net.DLL, I'm making an educated guess (based on the address in 
this .dmp) that the exception is occurring at

ThreadedSocketConnection::readMessage(String)

Thanks,
Rick
