Hi,

I recently ran ncat-test.pl under Cygwin and found quite a lot of
unexpected failures and some MSVC crash windows. In order to capture
them all, I set up a video recording program on the VM. Here's the
copied error message:

---------------------------
Microsoft Visual C++ Debug Library
---------------------------
Debug Error!

Program: ...n\home\d33tah\shared\ncat\ncat-env-ncatins\ncat\test\ncat.exe

R6010

- abort() has been called



(Press Retry to debug the application)
---------------------------
Abort   Retry   Ignore
---------------------------

The aborts happened on the following tests:

PASS --broker mode (tcp)
PASS --broker mode (tcp ssl)
FAIL --max-conns 1 --keep-open with exec (tcp)
FAIL --max-conns 1 --keep-open with exec (tcp ssl)
FAIL --max-conns 10 --keep-open with exec (tcp)
FAIL --max-conns 10 --keep-open with exec (tcp ssl)

Note that the tests happened on my ncat-env-conninfo branch, but my
previous tests on the code without my patches looked almost the same.
Also, I modified ncat-test.pl a bit, removing most of the sctp tests.
I made sure that the line numbers didn't change, though. Here's the
diff:

Oh, there's also problem with "--send-only client" tests - although in
the attached log they succeeded, in reality I had to kill Ncat for the
tests to continue because they obviously fell into an infinite loop.

I can re-run the tests if there's any more info you need. I can share
the video as well (30 megabytes).

Yours,
Jacek Wielemborek

I kind of accidentally fixed the "--send-only client" bug. The
solution's in r31702.
