Hi Mark,
Thanks a lot for quick response and some pointers . Here is the version
info' I found in mail.h. This header also contains this line: " Last
Edited: 19 November 2007 "
/* The Version */
#define CCLIENTVERSION "2007"
Here is the local variable info' for tcpstream from debugger if that
helps :
- stream 0x017258e8 {tcpstream=??? cred={dwLower=??? dwUpper=???
} context={dwLower=??? dwUpper=??? } ...} ssl_stream *
+ tcpstream CXX0030: Error: expression cannot be evaluated
tcp_stream *
+ cred {dwLower=??? dwUpper=??? } _SecHandle
+ context {dwLower=??? dwUpper=??? } _SecHandle
+ sizes {cbHeader=??? cbTrailer=??? cbMaximumMessage=??? ...}
_SecPkgContext_StreamSizes
bufsize CXX0030: Error: expression cannot be evaluated unsigned
int
ictr CXX0030: Error: expression cannot be evaluated int
+ iptr CXX0030: Error: expression cannot be evaluated char *
iextractr CXX0030: Error: expression cannot be evaluated
int
+ iextraptr CXX0030: Error: expression cannot be evaluated
char *
+ ibuf CXX0030: Error: expression cannot be evaluated char *
+ obuf CXX0030: Error: expression cannot be evaluated char *
Thanks,

Subject: Re: [Imap-uw] C-Client crashes on Vista
The first thing you should do is to determine which version of c-client
you have. Newer versions of c-client have a #define CCLIENTVERSION near
the start of mail.h. Your "April 08 as the date" confuses me; there was
no release version in April 2008 or on any April 8.
Please consider upgrading to the latest UW release (imap-2007e) and/or
working with me to get Panda IMAP (imap-2008) which has quite a bit that
never got into UW.
The stack trace is also a bit confusing. ssl_w2k.c was last changed on
January 13, 2008 during imap-2007b development. Line 622 is a comment,
and ssl_host() is several lines lower, so this tends to confirm that you
have an older version.
The stack trace omits some frames. imap_parse_header() calls net_host()
which calls ssl_host(), but the stack trace implies a direct call. This
is probably due to compiling with optimization.
It isn't at all clear to me why ssl_host() would crash. All it does is
call tcp_host() with stream->tcpstream as an argument. Since the
ssl_stream is non-null and a reasonable address (0x017258e8),
stream->tcpstream should have resolved.
Other than that, the stack looks reasonable; this is a reasonable flow
from mail_fetch_structure().
So, what you should do in the debugger at the point of the crash is take
a look at stream (the ssl_stream, not the mail_stream at higher levels)
and make sure that its contents are reasonable. stream->tcpstream
should be non-null and point to a tcp_stream.
Last, but not least, this code is used extensively under Vista
(including by me). This is the first that I have heard of this crash.
So it is possible that there is something that your application may be
doing to corrupt memory.
Unfortunately, this is probably all the help that I can offer you, at
least for now. If you discover something interesting in the ssl_stream
or tcp_stream, I may be able to offer some insights. Note that I no
longer support UW IMAP in any way.
Good luck!
