Hi,

I have a problem when using libcurl with openSSL. My program crashes
immediately after the last CURLOPT_WRITEFUNCTION callback when libcurl is
closing the connection. It crashes at the following line in "ssl_lib.c":

X509_STORE_free(a->cert_store);

I failed to debug deeper than this.

I know that this is in openSSL and that this mail perhaps should have been
posted to another mailing list.

The callstack looks like this just before X509_STORE_free is called.

SSL_CTX_free(ssl_ctx_st * 0x009baad0) line 1256
Curl_SSL_Close(connectdata * 0x00ab4b98) line 445 + 15 bytes
Curl_disconnect(connectdata * 0x00ab4b98) line 1034 + 9 bytes
Curl_done(connectdata * 0x00ab4b98) line 2413 + 9 bytes
Curl_perform(SessionHandle * 0x00aa0068) line 1166 + 9 bytes
curl_easy_perform(void * 0x00aa0068) line 245 + 9 bytes

After the call fails the callstack looks like:

_free_dbg_lk(void * 0x009b9abd, int 1) line 1011 + 48 bytes
_free_dbg(void * 0x009b9abd, int 1) line 970 + 13 bytes
