I have not commented out both gvl_align_data lines (#684 and #1009) in
gvl_calc.c, but fixed variable initialization in trunk r54866. Please
test.

Also, isosurfaces do not display. But there is no crash for either isosurfaces or slices when I comment out this line. On the face of it, a memory issue related to display in the Z dimension is causing a crash. Commenting out calls to gvl_align_data in gvl_calc_c stops the crash and stops display in the Z dimension. There is also something called gvl_calc2_c in this folder. Its code is very similar to gvl_calc_c
