Bug#600376: perl-base: memory leak in 'use v5.8'

[onlyjob.]

Package: perl-base
Version: 5.10.1-14
Severity: normal

There is a memory leak in 'use v5.8;' statement. (Version or notation not
important)

Can be reproduced using following command:
    bash -c 'ulimit -v 70000; perl -e "eval q{use v5.8} while 1;"'

Execution of this command terminates with 'Out of memory!' error after several
seconds.
This is happening on both x86 and x86_64.

Not a big problem, but for persistent FastCGI dispatcher EVALing or DOing other
scripts it is a cause of memory leak.

Thank you.
