Comment (by juhpetersen):
Additional note: this seems not to affect ghc-7.4.1 (Fedora 18) which
surprised me.
So so far only seen on ghc-7.4.2 and ghc-7.6.3.

Everyone,
That's fantastic that the record issue is being worked on as a GSoC
project!
Adam,
Thanks for doing this! How is it going? Do you have a blog with your
progress or something for us to follow?

Comment (by juhpetersen):
Hi Edward, thanks I tried that and indeed .note.GNU-stack is present and
not set executable
(with unpatched ghc-7.4.2 I see that the ghc*_1.o file has .note.GNU-stack
set executable
so your patch seems to be working).
(I noticed that HSbase*.o has executable stack set but I guess that should
not affect this, right?)

Comment (by ezyang):
OK, I adjusted this a little bit:
{{{
commit 3a8c50111d5a92594f5c2f1b2b96a7c1cfab82eb
Author: Edward Z. Yang <ezyang(a)mit.edu>
Date: Wed Jul 10 13:10:32 2013 -0700
Add LOCK_CLOSURE macro for use in C--, which inlines the capability
check.
This patch also tweaks lockClosure to be INLINE_HEADER, so C-- clients
don't accidentally use them and updates some other code which locks
closures
to do the capability check.
Signed-off-by: Edward Z. Yang <ezyang(a)mit.edu>
}}}

Comment (by igloo):
Given the existing code, I assumed that we want to avoid the overhead of a
C function call.
