Maybe a hardend thing?

disable mprotect(), see pax-utils eclass.
Also, is this mksnapshot thingy a test? At least it looks like it is..

[Comment 4 Mike Gilbert 2011-10-15 17:49:19 UTC]

As I understand it, mksnapshot builds a "heap image" to enhance v8's performance at startup.

We are disabling this for www-client/chromium based on host-is-pax, so I have done the same here.

Can you give it another test ago?

Why don't you try to disable mprotect first?

mksnapshot is built as a dependency of the main target, so I don't have an opportunity to call pax-mark before the build system executes it.

Yes, I'll do

Fixed, good job ;)
