error code = -24
Unknown error code


In vfe/vfesession.cpp, I made a small change to print out the error code (I know I
could have used a debugger for this...):

const char *vfeSession::GetErrorString(int code) const
{
   if (code == -1)
     code = m_LastError;

   switch (code)
   {
     case vfeNoError:
       return "No error";
   .
   .
   .
   }
   // added djconnel Jan2008
   fprintf(stderr, "error code = %d\n", code);

   return "Unknown error code";
}




In vfe/unix/unixconsole.cpp :

void ErrorExit(vfeSession *session)
{
	fprintf(stderr, "%s\n", session->GetErrorString());
	session->Shutdown();
	delete session;
	exit(RETURN_ERROR);
}


Pardon my c++ gross ignorance, but I'm not sure where the value of code is passed to
the GetErrorString(), although somehow it's getting an illegal value....  independent
of the source file.

You did patch vfe.cpp, did you?

If you didn't, then the unknown error is no surprise since 2009-01-01, 00:00.

No :).  I've been in southeast Asia, not following updates...

Ahh, the famous Y(2K+9) problem :)

I deleted the offending time check.

It seems to me this is an error: it throws an exception code, defined in
source/base/pov_err.h , yet enumerated values defined in vfe/vfesession.h are assumed
by vfeSession::GetErrorString(int code), which ends up getting invoked.

I'm not going to spend any time on it, though.... easy enough to delete the check.
