No, este lepsi je program gdb (debugger):

$ ftp sunsite
Connected to sunsite.uakom.sk.
220 sunsite.uakom.sk FTP server (Version wu-2.5.0(1) Fri Jun 4 12:35:02 MET DST 1999) ready.
Name (sunsite:bendik): [stlacil som ^\] Quit (core dumped)
$ gdb -core core
[...]
Core was generated by `ftp sunsite'.
Program terminated with signal 3, Quit.
#0  0x400e4a44 in ?? ()
(gdb)

Ak je program skompilovany s volbou -g (debug info), tak sa ta pekne
zistit, kde spadol (beznejsi ako 3 je signal 11 ;)

Generovanie core-suborov sa da v shelli ovladat pomocou prikazov 'limit
core XXX' (tcsh) a 'ulimit -c XXX' (bash).
