Bug#814080: plack::handler::apache2/plack::util crashes after a while

[Alexander Zangerl]

Package: libplack-perl
Version: 1.0033-1
Severity: normal

i've got a few small web applications written in mojolicious that
i run via

 SetHandler perl-script
 PerlResponseHandler Plack::Handler::Apache2
 PerlSetVar psgi_app /path/to/the/app
 PerlSetEnv PLACK_ENV "production"

ie, within the apache and using mod_perl. this starts up just fine, works
a few days, then inevitably crashes with the following error message:

Feb 8 08:19:21 <mybox> apache2[3425]: [perl:error] [pid 3425:tid...]
[client ...] Error while loading /path/to/the/app: Global symbol
"$_file" requires explicit package name at (eval 8) line 3.\n,
referer: somereferrer

the code in question is _load_sandbox() in plack::util, but it's not clear to
my why this would work once but not more than once.

the mojolicious apps in question have all been cleared of any findbin, by
the way; they only use 'use lib "$ENV{MOJO_HOME}/lib";' because i suspected
findbin as the cause of the problem - but neither findbin with ->again nor
findbin without changed the behaviour any.

even more puzzling is the fact that this very same code and config has been
working reliably for years on wheezy (with its apache2.2 and whatever version
of plack that wheezy came with).

i've been experiencing this problem only  since i upgraded to squeeze and
its perl, plack and apache versions.
