Confirmed by visual inspection of the assembly code.
What seems to be happening is this:
After if conversion we have (pseudo code)
a ? alpha.style = 1
a ? ...
!a ? alpha.style = 2
!a ? ...
inlined_memcpy(newinfo->fig->alpha, alpha, sizeof (alpha)
and this is transformed by the scheduler into
a ? alpha.style = 1
a ? ...
!a ? ...
inlined_memcpy(newinfo->fig->alpha, alpha, sizeof (alpha))
!a ? alpha.style = 2
That is, alpha.style is only set to 2 after alpha has been copied elsewhere.
Disabling sched-2 also avoids the problem.
