Summary: libcurl handle leak in Windows

Initial Comment:
In file 'hostthre.c' (Libcurl version 7.14.0) a new thread is
created:

/#ifdef _WIN32_WCE
  td->thread_hnd = (HANDLE) CreateThread(NULL, 0,
                                         
(LPTHREAD_START_ROUTINE) THREAD_FUNC,
                                         conn, 0, &td->thread_id);
  TRACE(("Created thread; %d\n", td->thread_id));
#else
  td->thread_hnd = (HANDLE) _beginthreadex(NULL, 0,
THREAD_FUNC,
                                           conn, 0, &td->thread_id);
#endif

The only place that CloseHandle is called on td-
>thread_hnd is in the function 'Curl_wait_for_resolv' in
the same file. HOWEVER, 'Curl_wait_for_resolv' does
not get called when I step through the code. Therefore
thread handles are being leaked.

Keep in mind that CreateThread/_beginthreadex DOES
get called.

Thanks,

I've forwarded this bug report to the libcurl mailing list.
I don't personally have nor develop under Windows.

I assume you have verified emperically that libcurl leaks
this, or only by reading the source?

Can you please provide us with an as simple as possible
source code that uses libcurl and makes this leak occur?
