--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The inline-asm is not marking as clobbering memory.
In this case since you just pass the address of the variable, gcc does not know
the inline-asm will read memory at all, it deletes the store. Anyways adding
"memory" as a clobber to the inline-asm, fixes the issue.
