Hi everyone,

I'm using Microsoft's CRT debugging facilities (crtdbg.h) for memory
leak detection in my application. The debug handler reports two memory
leaks when using libcurl's global initialisation and clean up:

  curl_global_init(CURL_GLOBAL_ALL);
  curl_global_cleanup();

When calling those two functions (no other function from libcurl is
used) and exiting, I receive the following dump:

Detected memory leaks!
Dumping objects ->
{2548} normal block at 0x01207BB8, 16 bytes long.
 Data: < > 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
{2547} normal block at 0x01207AD0, 20 bytes long.
 Data: < { > 00 00 00 00 B8 7B 20 01 00 00 00 00 04 00 00 00
Object dump complete.

I believe it is an OpenSSL related problem because the memory leak
goes away when I comment out the call to Curl_ssl_init() in
curl_global_init().

I made sure that I have HAVE_CRYPTO_CLEANUP_ALL_EX_DATA defined, which
was reported as a memory leak in a previous thread.

I wonder if this is a known problem. My configuration: libcurl 7.19.0,
OpenSSL 0.9.8i, MS VC++ 2005 SP1

Thanks,
Claus
