It does not have the problem on version 0.2.0.

Loop scheduling missing MSTORE/jump dependency

I have a custom array interface implementation that takes 4 steps to complete a write (rather than the default of 2), I'm having issues where if I use it in a loop the the last 2 steps get truncated. I've changed the n_step being used to 4 and the increased the latency of MSTORE and I've traced it back to an issue in the scheduler. It appears that the jump in the forbody back to the fortest does not depend on mstores in the loop body:

Here's the schedule for the block:

Node 6046 0 0:0 @cond565:bool = (i#2:int[32] < @t560:int[32]) @top.const_multiply_fortest2
Node 608c 1 0:1 cjump @cond565:bool ? @top.const_multiply_forbody3, @top.const_multiply_forelse5 @top.const_multiply_fortest2
Node ba6a 0 0:3 @t566:int[32] = ys:list[int[32]][i#2:int[32]] @top.const_multiply_forbody3
Node 459a 0 0:0 i#3:int[32] = (i#2:int[32] + 0x1) @top.const_multiply_forbody3
Node ba5c 1 3:3 t:int[32] = (@t566:int[32] * x:int[32]) @top.const_multiply_forbody3
Node ba4e 2 3:6 mstore(ys:list[int[32]][i#2:int[32]], t:int[32]) @top.const_multiply_forbody3
Node bacc 3 3:4 i#2:int[32] = i#3:int[32] @top.const_multiply_forbody3
Node 45af 4 4:5 jump @top.const_multiply_fortest2 'L' @top.const_multiply_forbody3

You can see that the mstore ends on state 6 but the jump back begins on state 4. The state reducer then removes states 5, 6 because they can't be reached.
