call_before_step_each_stage=False passes uninitialized aux to riemann solver

[GustafssonJonathan]

For sharpclaw passing to following options:
solver.aux_time_de = True
solver.call_before_step_each_stage = False

Seems to pass a uninitialized aux array to the Fortran Riemann solver. solver.call_before_step_each_stage = True works as expected.

Could you link to a full example that reproduces this behavior? Thanks.

No problem. Here is a modified version of acoustics_2d_variable
The solver gives nan when
solver.before_step_each_stage = False
and works correctly when
solver.before_step_each_stage = True
