Enabling core files (Debugging->General)

Core files are handy to have around if your program crashes with a SEGV, bus error, or if it raises an abort(). You can dig into the core file with gdb There are two ways to enable core files:

• in your C shell do
  % limit coredumpsize unlimited
  (you can put this into your .cshrc. I don't know what to do for bash)

• Or in your program do
  struct rlimit corelimit = { RLIM_INFINITY, RLIM_INFINITY };
setrlimit (RLIMIT_CORE, &corelimit); You may need to also add
  #include <sys/types.h>
#include <sys/time.h>
#include <sys/resource.h>

Core files seem to be getting dumped into /cores, rather than the directory the program was run from.
