Hello,

I'm fine with reverting for now. But could you give me a way to reproduce this error?

I've not seen crashes on either linux and windows in various configs.

Cheers,
Andreas

OK I have verified that

  *   This split_marker crash happens on a clean HEAD build
  *   Reverting "NCG: New code layout algorithm.", 575515b4909f3d77b3d31f2f6c22d14a92d8b8e0, solves the problem.
Andreas: I propose to revert in HEAD unless you have a rapid fix, or believe that is somehow my fault.
(Or maybe someone else can revert.)


Simon, are you using split-objs by any chance?

Regardless, yes, let's revert until we work out what is going on here.

Cheers,
