[svk-devel] double free or corruption

Mon Feb 26 05:57:20 EST 2007

I'm seeing output like the following reasonably often when using svk
[primarily svk up].
I'm guessing that SVK is pure-perl, but does anyone have any suggestion
what's really at fault here?

Is it a buggy perl, or has something pulled the rug out from underneath
it?
