Alas even the workaround I had used of disabling the debugging code did not make it stable, it just delayed it and the memory trashing seemed to move elsewhere. Since my code was in production I could no longer afford these random crashes and gave up, moving from curl_easy_recv to just using plain recv() which fixed all my problems, so I have been unable to debug it any further.

** [bugs:#1170] curl_easy_recv() ends in crash within Curl_recv_plain**

In the cgminer project \( https://github.com/ckolivas/cgminer \) I am using libcurl version 7.28.1 compiled for mingw32 and using curl easy recv on the raw socket returned. Dropping internet connection on windows\* with this compiled version I get a reproducible crash on the following line:
sendf.c:353
failf\(conn->data, "Recv failure: %s", Curl\_strerror\(conn, err\)\);
Debugging is disabled in the build, but this line reliably crashes on mingw32. Commenting out the line entirely the crash goes away. This can be reproduced without dropping internet connection on windows by killing the tcp connection with currports. I don't know the exact mechanism of the crash without digging further but I suspect conn->data is dereferenced.
