What's the fix for the "assertion failed" error?

2010-09-13 20:15

I get the same error:

Assertion failed: s->gsslib, file putty\ssh.c, line 7970

This is using AD integrated Kerberos on the server. I have a 'kerberized' version of Putty installed, if that makes any difference. You mentioned that this is resolved, but I don't see any information on what the 'fix' is, and I'm running version 4.2.8 (build 818).

Thanks,
Chad

I've meant the debug log as described in the email I've sent you.

Anyway, I was able to resolve the problem with help of another user.
This bug is being tracked already.

Thanks, but I need log file generated by the debug version.

The log below doesn't seems to indicate anything as it's cut short. Is there a more detailed log created? What's weird is that it seemed to work one time, but I haven't been able to get it working since.
