[GEMPAK #HTT-869970]: decoders for Mac OS 10.7?

Susan,

I'm convinced the segfault in this case is coming from an attempt to write 
error messages to a log, so I've attached an edited version of decode_g2gnum.c 
for you to place in $NAWIPS/unidata/ldmbridge/dcgrib2/, after which you should 
cd to this directory and execute "make clean;make all;make install" to rebuild 
dcgrib2.

Thing is, this is likely a wider problem with glibc, which means if fixes the 
error in decode_g2gnum we might see the same error elsewhere.  

Give this a try, and if we find that it works I can prepare a small OS X patch 
and send it your way.
