c++ Stop libcurl crypto throwing Signals

I have a c++ 11 program and am using libcurl with the curl_easy wrappers to contact a remote server. I am using SSL, have set the CURLOPT_NO_SIGNAL to stop curl from throwing signals and also recompiled curl with cares. However I still get the following signal thrown by the underlying ssl library.

/main(_Z13signalHandleri+0x464) [0x65230]
/lib/libc.so.6(__default_sa_restorer_v2+0) [0x40d3ae50]

I have tried wrapping the curl_easy_perform with a try/catch but for some reason it doesnt seem to catch the signal

try
   {
      curl_easy_perform()
   }
   catch (int signal)
    {

    }
    catch (...)
    {

    }
