Comment (by sjamaan):

 Note that this particular situation will have been fixed in CHICKEN 5
 already; we simply encode flonums as a packed byte sequence, and "large"
 fixnums (> 30 bits) as bignums, which will be simplified to fixnums after
 reading. The bignum reader doesn't use `strtod`. Note that there's still
 some compatibility code in runtime.c that still triggers the old code
 path.  This is to make it possible to compile CHICKEN 5 through a boot-
 chicken with CHICKEN 4.

 Regardless of this being fixed in CHICKEN 5, there could still be issues
 lurking due to locale mismatch, we should really try to figure out a way
 to catch these stupid bugs :(
