create a core file like:

[pmuldoon@localhost pkglibdir]$ `pwd`/funit-child 10000 --busy-loop &
[1] 9176

9176.9176: argv[0]=/home/pmuldoon/frysk_bin/frysk-core/frysk/pkglibdir/funit-child
9176.9176: argv[1]=10000
9176.9176: argv[2]=--busy-loop
9176.9176: starting 9176
9176.9176: new thread 9176.9176

[pmuldoon@localhost pkglibdir]$ cd ..
[pmuldoon@localhost frysk]$ cd bindir/
[pmuldoon@localhost bindir]$ ./fcore 9176

Then do a fstack -a dump on it:

[pmuldoon@localhost bindir]$ ./fstack -a core.9176

Then load that same core file into fhpd:

[pmuldoon@localhost bindir]$ ./fhpd
(fhpd) core core.9176
