[Developers] buffer overflow

[John Sibert]

Does any one understand this? The program appears to abort during 
startup. The problem developed overnight without me making any changes 
to the code.  If I compile without optimization, the program does not 
abort, but still behaves strangely.

I'm using ADMB revision 123.
