segmentation fault if host unknown

[GoogleCodeExporter]

When specifying an unknown host, a segmentation fault occurs:
mysql> select http_get('http://example.invalid/');
ERROR 2013 (HY000): Lost connection to MySQL server during query
mysql> 

The mysql error log says "mysqld got signal 11 ;"


After some debugging I found that in that case result->res ist still NULL after 
curl_easy_perform. The error is caused by 
strcopy(res->result, "")


The attached mysql-udf-http.c resolves the issue.
