If you can reproduce it with build-porting64-gcc-portability, I'll
jump on it immediately.

If not, it will have to wait. My plan is to investigate the problems
introduced by the various optimizations (that are turned off in
--enable-portability builds) one by one:
  -DNO_ASM -DNO_ARI_ASM -DNO_SP_ASM
  -DNO_FAST_DISPATCH
  -DNO_FAST_FLOAT -DNO_FAST_DOUBLE
  -DNO_ALLOCA
  -DNO_ADDRESS_SPACE_ASSUMPTIONS
  -DNO_GENERATIONAL_GC
If the problem is not reproducible with these -DNO* options, an
important data point would be: what is the maximum set of such options
that makes the problem disappear?
