Hi Curl-users,

I am using Curl library (libcurl.so.4) interface for Http get request,
sending HTTP request to HPOCMP server but client application is giving core
dump when i run by using purify tool .

With out Purify, client application running fine and not giving any code
dump.

Kindly share/suggest how to solve this issue and below is the purify output,
