20001201: Question: Gempak5.6 SIGSEGV with sfchck

Stephen,

This may be the problem I fixed and reported to NCEP at:
http://www.unidata.ucar.edu/glimpse/gempak/3935

This fix will be in my 5.6a release which I'm trying to get
out in the next week. Until then, you can edit your:
$GEMPAK/source/programs/sf/sfchck/sfchck.f file and change:
head*132 to head*512 
and 
string*132 to string*512

Then recompile with:

cd $GEMPAK/source/programs/sf/sfchck
make clean
make all
make install
make clean

See if this fixes your problem.
