Pablo Optimization Issue?

On branch computed-UTF-if-hierarchy, commit #61e5318a, I am getting a Pablo error.

cameron@cs-osl-11:~/parabix-devel/build12$ perf stat bin/ucount '\p{Letter}' ~/Wikibooks/wiki-books-all.xml -thread-num=1 -UseComputedUTFHierarchy -IfEmbeddingCostThreshhold=17 -EnableCycleCounter -ShowOptimizedPablo=pv -ShowPablo=pb

produces a Pablo error message.

LLVM ERROR: PabloCompiler: not_1961 was used before definition

The unoptimized Pablo has these in the right order:

cameron@cs-osl-11:~/parabix-devel/build12$ grep -rn not_1961 pb
12196:                not_1961 = ~lookahead_21
12200:                and_5486 = not_1961 & or_2138

The optimized Pablo shows the error.

cameron@cs-osl-11:~/parabix-devel/build12$ grep -rn not_1961 pv
10513:                                    and_5486 = not_1961 & or_2138
10625:                not_1961 = ~lookahead_21
12814:                        Byte_0_1f_2 = InFile(not_1961)
13035:                            and_7067 = not_1961 & or_2881
