I think it is not correct to use HTProfile_delete( ) before any other
function call. HTProfile_delete must be
the last function call you want to use for the whole program since it
closes every resource the program
has established. If you move HTProfile_delete() out of terminate_handler()
and move it to the end of
main(), it probably works.

Hi my name i Patrik from Sweden and i have for two weeks ago start to
use libwww, for internet application.
I try to build an application for posting and receiving data.
I start to use postform.c example and it works nice until I change
the terminal_handler function to use return 1 or
0 instead exit(0) and some strange memory error oocured.
I have try to do as people said in the discussion on libwww's homepage .I
try to stop (HTEventList_stopLoop();
the eventloop in the end of the terminal_handler function without result.
Do
you think anybody can help me.
The progrma looks like:
