Description Petr Pisar 2012-06-21 09:26:58 UTC
The `eval' and `do' functions should clear $@ variable on success. However this does not happen always:

eval { die "shouldn't see this\n" };
do 'no such file';
warn $@ if $@;

This has been fixed in upstream commit:

Author: Eric Brine <ikegami@adaelis.com>
Date:   Mon Jun 18 14:56:32 2012 -0400

    RT#113730 - $@ should be cleared on "do" IO error.


Tested with perl-5.14.2-198.fc16.x86_64. All Fedoras are affected probably.
