I suspect a problem at the end of several CGI's execution. In extinfo, for example, at the end of main(), it calls free_memory, and then free_extended_data. But free_memory itself calls free_object_data, which calls free_extended_data. So, free_extended_data is called twice and, the second time, it frees again his pointers (that's why I try to always set the pointers to NULL after freeing them, even when I won't use them any more). Not sure, but if I am right, one of the calls should be suppressed. </BODY> </HTML>
