[Kirk Reiser]

A segfault or segmentation fault or violation is when a pointer in the
code tries to access memory outside the range allocated as user space
by the operating system.  I really mean outside your user memory
space.  There are many reasons for getting segfaults but the most
common is when the programmer didn't use a memory pointer correctly in
their code.  In a program which doesn't have all of it's components
installed, a segfault will occur because the program which faulted
tried to access memory, such as shared, and it wasn't available.  The
o.s. says, woops you're trying to get out of your allowable range,
naughty naughty.
