Hi Evan,

actually those wrong array index will never be used thanks to the
following lines 6503 and 6622:
if (msg_str == NULL)
{
   ...
}
else
{
   use ett_tree
}
and
if (msg_str == NULL) return;
...
use dtap_msg_fcn

So the invalid memory accesses will never occur.
I made it a bit more obvious in r48520.

Unless you spotted another place in the source code, I suggest closing
bug 8517.

Regards,
Pascal.
