More specifically, we do not need to assume that every exception are deadly
but a less imperative constraint.
We need to assume that there does not exist any condition that goes in this
branch and does not bring to an exit.
if((exitstatus && eflag) || (e)) {
/* memory leak is not a problem, we are exiting */
} else {
For example (exitstatus && eflag) == true does not means in general that
the ash will exit because
false || true
However, when it comes to this point it is always true that it will exit.
So, a more general statement about (e) wil be (isdeadly(e)) so if e != 0
but it has a value for which we know it is not deadly, we can separate it.
Unfortunately, at the moment it is not clear for me which kind of value
could receive e and why.
This is the reason for which I cannot grant the right condition to happen
at 100%.
