Hi,

GC v7+ uses AO_store_release for unlocking, so the problem, as Zoltan said, does not apply to.

Regards.

Hi,
 I think the problem no longer applies to the current GC sources, only to older versions (6.4 etc).

Hello,
A colleague of mine recently tracked a SMP related bug on ARM. The issue is that gc_locks.h doesn't define GC_clearand arm requires proper fencing.
Here's the patch he applied:  https://github.com/mono/mono/commit/26fd8d13fcb113e868034a9fae94d5862f7923eb (https://github.com/mono/mono/commit/26fd8d13fcb113e868034a9fae94d5862f7923eb) 

Cheers,Rodrigo Kumpera
