I'll see if I can track down exactly where it's getting confused. - Mitch On 02/29/2012 06:44 PM, James K.

On the error path from a connection failure, ct_connect() calls a host of free_* routines, some of which call other freers, some through pointers. It's possible something goes wrong. Not obvious, but possible. You could attack it through your malloc(3). Most C standard libraries have ways to make invalid frees fail in a noisy way.
