Segmentation fault Causes

[bjorn rohde jensen]

Hi there,

  Segmentation faults are signals delivered from the operating
system to a process to inform it, that the process has attempted
to access memory outside its address space. Common causes are
forgetting to initialise a pointer before use or using something,
which is not a pointer, as a pointer.
  You might want to compile with debug info and run the program
under a debug'er. It should provide you with the exact line,
where the segfault is generated. If you are fairly lucky, the
reason will be also be quite apparent.

Yours sincerely,

Bjorn
