    We can easily reproduce this bug on version 5.0.7 and 5.0.5 on Slackware
    Linux and Phoenix and Mozilla browsers. You can choose Netscape or NCSA
    compatibile browser in Adobe preferences, and WWWLaunchNetscape and 
    WWWLaunchNCSA functions. 
    
    You should not have problem with this bug. It is quite simple to
    reproduce. Just create .pdf file with long link, execute adobe, open
    this file, then attach to it using gdb, put breakpoint on
    WWWLaunchNetscape and click on link. There is loop in this function that
    do something like this:
    
        while(*src != '\0')
            *dst++ = *src++;
    
    As you can see there is no bounds checking.
    
    best regards
