Since I don't have access to the readnoaaport code, I can't do much
here.   But a signal 11 is a segmentation fault and its occuring on the
NWSTG2 channel.   I know NCEP has been doing some things with the CCB
header and multiple routing sequences.  I know in the past most software
only accounted for one or at most two.  If the readnoaaport code only
accounts for a limited number, this could be a problem.  I can't think
of much else that would cause a problem.  I can trap for this here and
see if this is an issue.
