Use of uninitialized value

[pigen]

Hello,

After upgrading to needrestart 2.11 ( #57 ) from jessie backport the postfix service is always "need restart" (it's fixed 2.10, or not? #46 ), and I get these warnings all the time:

Use of uninitialized value $testp in stat at /usr/sbin/needrestart line 462, line 1.

Thanks, the handling of file existence check was broken for library mappings in (/var)?/tmp.
