Proposed fix

It seems like typo in the ASM. The 1.53 seems to be also affected.
Comment 2 Jaroslav Škarvada 2013-08-29 09:27:53 EDT
Decreasing the version to f20.
Comment 3 Petr Machata 2013-08-29 18:25:52 EDT
Filed upstream as https://svn.boost.org/trac/boost/ticket/9065
I think a better fix is simply swapping the incoming arguments of the inline assembly block, as that way they match the incoming arguments of the function itself.  That's what I'll apply in F 19+.
