Consider the code:
record R
{
class C
{
proc ~C()
{
writeln("in ~C");
}
}
var c : C;
proc R()
{
c = new C();
}
proc ~R()
{
writeln("in ~R");
delete c;
}
}
proc doit() {
var x: R;
}
doit();
Description:
Expected behaviour should be that, x calls destructor once when leaving
scope. But for some reason the destructor is called at least twice:
in ~R
in ~C
in ~R
in ~C
bug1.chpl:3: error: attempt to dereference nil
While (in case when 'class C') isn't nested:
in ~R
in ~C
Also, changing record to class and calling all destructors manually doesn't
give this behaviour.
All the info you probably won't need:
