Comment (by strk):

 So I think one possible fix here would be to NOT rely on an external
 function for inizializing allocators. This model (currently in use) was
 long abandoned in liblwgeom, substituted by an initialization function
 explicitly registering callbacks into the statically linked library.

 But I'm afraid this would need change in the old library, which isn't
 feasible.

 Still, if the new library moves to the new model it can stop exporting the
 'rt_init_allocators' symbol, and thus the resolver should find the correct
 one in the old library.
