in reply to How to kill perl?

perl -e 'undef %:: or die'

I'm testing a fix to this in bleadperl and it appears to have it fixed. Should be available later today. By the way...

perl -e 'undef %:: or warn'

was equally broken.

    I don't think this really has to do with die specifically. For example,

    perl -e 'undef %::; sub{}->()'
    crashes too. Lots of thing crash when you've totalled the defstash! But perhaps that just indicates a pervasive assumption, which really needs to be fixed in lots of different places.

    See also bug 32401.

    PS. Getting a bit more targeted:

    perl -e 'delete $::{"@"}; warn' ;# crashes perl -e 'delete $::{"@"}; sub{}->()' ;# doesn't crash perl -e 'delete $::{"_"}; warn' ;# doesn't crash perl -e 'delete $::{"_"}; sub{}->()' ;# crashes

    I suppose that wiping out important global variables oughtn't to be allowed, really.

    PPS. Let's see what the p5p hive mind thinks.

    Ugh! Spoke too soon. My fix kills some of the more exotic functionality of die(). Well, at least I know I'm on the right track.
