As discussed in the upstream ticket, the above got fixed for 5.14,
but this still triggers the malloc bomb:

 perl -le 'open FILE, "<", \($f=*STDIN) or die $!; print $_ while <FILE>;'

This is strictly speaking not a regression from squeeze as it didn't
work properly there either (it ended up reading random memory), but
the failure mode is a lot worse now.

The issue was fixed upstream in 5.14.3 with the attached patch.
I think this is a candidate for wheezy if it isn't too late.
