Devel::Cover error from Storable

[Kevin Scaldeferri]

My unit test suite recently started spitting out this error when run  
under Devel::Cover.  It runs normally and successfully without.  Has  
anyone seen this before:

Magic number checking on storable file failed at ../../lib/Storable.pm  
(autosplit into ../../lib/auto/Storable/_retrieve.al) line 323, at  
/home/kevin/lib/perl5/site_perl/5.8.0/i686-linux-64int/Devel/Cover/DB/ 
Structure.pm line 249
END failed--call queue aborted.

It seems to infect a certain test case, and then every subsequent test  
produces this, and fails.

The only clue I have at the moment is that the test case in question  
forks a couple times and is fairly IPC heavy.  I'm not sure if I can  
provide a simple case to reproduce it, as this is pretty proprietary  
:-(


Thanks,
Kevin
