Help...HTEventList_stopLoop()

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:
