[4.0] Assert error in vmod_clean()

[jeromemacias]

First, thanks for this amazing plugin!

Some times I have this Panic message:

Assert error in vmod_clean(), vmod_cookie.c line 233:

Maybe I can give some more details if you need.
Thanks.

Are you using the latest version from git master?

Are you seeing multiple ones like this, or different panics?

[jeromemacias]

I compiled it at commit b1fc260.

I have multiple ones like this one, always the same one.

Hi. Please try the 4.0 branch now. (3a2a9ae).

Hi. Did this fix your issue?
(timeout after july 3rd)

Sorry, I will not have enough time to make any test (and I don't work on the related project anymore).
As other tickets on the same subject have been closed, I considered than the bug had been fixed.
Thanks.
