Re: [expert] cdrom boot
I did see that type of behavior when I was trying to install V7.02 from a slow CDROM, 16X. When I connected a 48X, and ran it from there, all installed fine.

A good linux programming book will explain the most frequently used signals. Signal 11 is a segmentation violation meaning the program tried to do something with memory it wasn't supposed to, eg. dereferencing a null pointer. Tony

Where/how does one find more info as to what is actually causing these seg faults, or even some kind of diagnostic routine? I've been getting lots recently, even after popping every ic on I can find they continue to show up kinda/sorta/abit like too often while compiling from gcc. I'm been running a 64mb Pentium 133 Soyo mobo quite happily for around 9 months on L-M 6 and 7. Cheers John

GCC is usually rock solid unless the underlying hardware is faulty. I believe you can get a backtrace from the gnu debugger if you're debugging a program, but if it's just from any random process it can be hard to tell what has happened. If you're SURE it's not hardware check for any 'core' files lying around as I think they can help the author of the program fix a problem, though some privileged processes are prevented from dumping a core file.
