I assume that you are running the binary "a.out"?? . The "segmentation
fault" refers to some sort of memory related problem, attempting to
access (write to, etc.), a block of memory that has not been properly
allocated, exceeding the limits of an array, etc. However it is
impossible to tell exactly why you are getting this error unless you
provide an example of your source code.
The process of pinpointing such memory related problems can be made
simpler by using the Gnu debugger (gdb), in conjunction with the
"Electric Fence" library. For instance you can compile a program,
foo.c, with the following options:
$ gcc -g -o foo foo.c -lncurses /usr/lib/libefence.a
and then run the debugger:
$ gdb foo
run
Investigate the info and man pages for "gdb" for information of the
debugging commands and useages. Also, check out $man libefence for
info on the "Electric Fence" malloc debugger.
