I have identified that one of our patch has closure. The executable stack is caused by function trampoline constructed on stack to support closure semantics. My preliminary testing with that closure removed really can turn the stack into non-executable so that I'm working on a fix to replace closure with other means to achieve the same thing.

The SR forwarded to openSUSE:Factory


Change the resolution to fixed.
