Where are these core files from?

[hop-frog]

I have found several core files in my home directory. I have not noticed any applications crashing. How do I determine what program is leaving these behind?
Thanks.

Open them up in bugbudy. They represent a crash that may or may not kill the running program. I have had a few with mplayer and yet the program does not crash but the video may be putting a strain on other libraries.

icarus@Daedalus ~ $ file core
core: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style, SVR4-style, from 'fortune'

I get them from odd things, firefox leaves some large cores when it dies on me at times :)

When I ran Mandrake it would dump a core whenever a signal was raised. So on segfaults and things like that it would dump the core to the local directory where the program had been running. I wonder if it's just certain distros that are setup this way as on SuSe a segfault doesn't generate a core file that gets left behind after an app crashes.
