there are several combinations that work with the pre-built pypy but not with
my local version (except one: if only intbounds is selected, neither works).

The largest set of combinations that does work is:

   intbounds:rewrite:virtualize:ffi

Several others don't crash, but raise (and again, not in the pre-built):

RPython traceback:
   File "implement_18.c", line 205492, in optimize_loop
   File "implement_19.c", line 86345, in _optimize_loop
   File "implement_19.c", line 202071, in UnrollOptimizer_propagate_all_forward
   File "implement_19.c", line 248573, in Optimizer_reconstruct_for_next_iteration
   File "implement_19.c", line 247560, in Optimization_reconstruct_for_next_iteration
Fatal RPython error: NotImplementedError

Does any of that ring a bell?

Changing gcc didn't work. For now, I'll live with it with the lower set of
options. It may after all still be something specific to my box which I intend
to replace sometime soon.

Thanks,
      Wim
