what exactly is a "segmentation fault"?

[rich <rehartma@artsci.wustl.edu>]

Howdy all,

I have just tried my 1st attempt at installing a non-debian package
(multitrack-2.2.tgz). I followed the instructions...

- place file in /usr/local

- tar xvfz multitrack-2.2.tgz

- cd multitrack-2.2

- make install

When I tried to run the program (by typing multitrack), I get a
"segmentation fault" error... I have heard this phrase before, but do
not know what it means... can anyone help, or at least point me in the
right direction?

Thanks in advance,

Rich
