I was able to reproduce the problem at the first shot. This time with a
very basic install of CVSNT 2.5.03.2260, no custom cvswrappers, SQLite
auditing turned on. Client and server running on Windows 2000 SP4 (same
machine actually), connection via :sspi: .

be sufficient to reproduce the problem (inside an existing sandbox):

echo blah>blah.bin
cvs add -kB blah.bin
cvs ci -m"" blah.bin
echo more blah>>blah.bin
cvs ci -m"" blah.bin

Each time I did this, my desktop firewall told me that CVSNT contacted
paris.nodomain.org (i.e. Tony's server) presumably to send a crash dump
(the trace indicated there was a ). I did this a few times so hopefully
Tony should have enough data to work on by now. Or is there anything
else you need?

After disabling the Audit plugin and rerunning the test the commit went
through without problems so it seems fairly certain to me that at least
in my case the problem is related to the auditing.

I actually did two runs: one with auditing on and another one with
auditing off and then compared the two traces in WinMerge. As I don't
know the code I have no idea if this is of any significance at all but
here I go nevertheless: Apart from the obvious stuff (i.e. (not)
loading the audit_trigger.dll and timestamps and tempfile names) there
were only two notable differences up to the point where the error
occurred and that were calls to rcsbuf_fill and calls to
GetUnixFileModeNtEA. E.g.:

Failed trace:     S -> rcsbuf_fill(0109A4D0,00000000,00000000,00000000)
Successful trace: S -> rcsbuf_fill(00F19970,00000000,00000000,00000000)

Failed trace:     S -> GetUnixFileModeNtEA(b,00000240) returns 0666
Successful trace: S -> GetUnixFileModeNtEA(b,00000244) returns 0666

(same values any time that occurred)

Hope this helps.

Cheers,
