Hello. I have lurned to run gdb to get simple answers I can understand, or at least I believe I have :-) I runned: "file core" and got "core: ELF 32-bit MSB core file SPARC Version 1, from 'python'" Then I runned: "gdb python core" and I got: "Core was generated by `/usr/local/bin/python /export/home/bmatt/iPersonal/z2.py -D'. Program terminated with signal 9, Killed." [snip] after reading all the symbols... [end snip] "#0 0xfef45c8c in realfree ()" ... Anyone has a clue what's thios? Thanks. /B Bruno Mattarollo <brunomadv@ciudad.com.ar> --- Python Powered <http://www.python.org/psa/>
