Hello,
I installed Const::Fast 0.007 using cpan install.
Const-Fast-0.006 works properly.

How to reproduce:
1. Create a file
./const-fast-test.pl:
use Const::Fast;
2. perl -c ./const-fast-test.pl
Actual results:
watch system memory usage rapidly increasing for the perl process running const-fast-test.pl
Expected results:
The following output:
Syntax OK.
Other cpan and system provided perl modules work without problems on all our systems.
Currently, we are using Const-Fast-0.006 without problems.
