ScalarWave thorn build error on Stampede

When I try to compile the Einstein toolkit on stampede, I get a series of errors relating to OpenMP loops. Each error is of the form:

 must have a loop-invariant increment of integer, pointer, or random access iterator type
    for (int tk = tiled_imin[2]; tk < tiled_imax[2]; tk += tile_size_l[2])

The error is definitely in the ScalarWave thorn, because disabling this thorn allows the toolkit to compile just fine.

Attached are the thornlist used and the error output. The command I used to compile was

sim build dgfe2 --thornlist=dgfe2_jm.th

Keyword: ScalarWave,OpenMP
