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.
