[gentoo-user] upgrade to perl 5.22.0 yields perl double free or corruption

Hi.  After upgrading to perl 5.22.0 which was a pain -- had to remove
all those virtuals -- I am now finding that a small perl program  which
connects to a mysql database yields the following when it exits:

*** Error in `perl': double free or corruption (!prev): 0x0000000001ed8610 ***

======= Memory map: ========

memory map  ommitted, if it is needed I can reproduce.

So, should I downgrade -- means removing all those virtuals again -- or
any other ideas would be appreciated.

I  am running the unstable gentoo, if you need more information, I can
include it.

Thanks in advance for any suggestions.
