static analysis: buffer overflow

Hello all,

The following error is generated by a static analysis of my application:

error #12048: buffer overflow: array index of "DESIND" is outside the bounds; array "DESIND" of size (1:5) is indexed by value 0

This error refers to the following file where DESIND is declared as:

CHARACTER*6  DESIND

and the offending line is:

DESIND ='IALFA'

Is this really a buffer overflow?  If so, how so?

Thanks,

Jim
