A character string provided in a data statement that is larger than declared
variable size causes an ICE.

This code is not standard conforming.  

gfortran should either:

a> Issue an error that the character string in the data statement cannot be
larger than the variable size.  { is smaller OK? or does it have to be exact for
character variables ? i dunno but it seems reasonable }

b> Issue a warning and truncate the string.


g77 does half of option (b). g77 misses the warning, but does not do any harm.


To duplicate:
