Where does it crash? Run Squid under GDB to find out.

Your test program is not a valid test of the code..

   char *something = "some string";

allocates a read-only string. Your need

   char *something = strdup("some string");

to test proper.

The GCC flag -Wwrite-strings will warn you about this.

Possible Negotiate helper responses:

Incremental negotiation:
TT blob

Successful authentication:
AF blob username

Failed authentication
NA blob Error message

Other failure
BH Error message
