void PL_abort_hook(PL_abort_hook_t)
Install a hook when abort/0 is executed. SWI-Prolog abort/0 is implemented using C setjmp()/longjmp() construct. The hooks are executed in the reverse order of their registration after the longjmp() took place and before the Prolog top level is reinvoked. The type PL_abort_hook_t is defined as:
typedef void (*PL_abort_hook_t)(void);
