#1630: Varnish crashes with long regex condition
-------------------------+----------------------
Reporter: huguesalary | Type: defect

Milestone: | Component: varnishd
Version: 4.0.2 | Severity: normal

-------------------------+----------------------
I just upgraded to from 3 (.0.5/6) to 4.0.2 on my debian system.

I converted my old varnish 3 code to 4.0.2. The varnish 3 code has been
working flawlessly for more than 2 years.

Now, in my varnish 4 VCL, everything works fine except for a very specific
piece of code that crashes varnish.

Some useful info:
