How to Reproduce

run under debugger after building with asan on windows.

Additional Background

suspect code in 
_mongoc_socket_setkeepalive_windows
 
      DWORD default_keepaliveinterval = 1000; /* 1 second */

      if (RegQueryValueEx(hKey, "KeepAliveTime", NULL, &type, (LPBYTE)&data, &data_size) == ERROR_SUCCESS) {
         if (type == REG_DWORD && data < keepalive.keepalivetime) {
            keepalive.keepalivetime = data;
Call to RegQueryValueEx should be RegQueryValueExA  (since param KeepAliveTime is not wide string - maybe explains failure in RtlInitUnicodeStringEx
