I can confirm James' observations. The problem looks like it may be difficult
to trace ... I can get the program to abort at line 812 in
$GEMPAK/source/programs/gui/nmap2/nmap_spfw.c:
if( ! (spftext = XtMalloc((Cardinal)flen))) {
However, inserting some printf statements, as well as some other innocuous code
changes, cause the error to appear further along in the code ... which likely
means that the actual error lies elsewhere. Since the Abort error often is
tied to a stack violation on OSX, I tried recompiling with the
-fno-stack-protector option, which corrects NMAP2 aborts on Ubuntu, but this
did not help. I suspect that there is some insidious buffer overflow hiding in
the NMAP2 code base. Maybe compiling with -Wall may turn up something.
In the meantime, James, you can still load your .spf files in NMAP2 on OSX by
using the command line option to load spf files ... e.g., "nmap2 -as
sample.spf".
I also can confirm the problem with loading vg files on OSX.
Cheers,
Kevin

Shoot. That is ugly. I don't even have access to a modern Mac OS to try to
debug. You would need to use a debugger with the "-g" flag at compile time, or
add some stdout code with fflush() calls to try to find the issue.
