It generates a wasted empty array for each `super` call though.
It should be fixed in the future, if possible.

Yukihiro "Matz" Matsumoto 2837de95fe Prevent splicing big recursive arrrays; ref #3679 
We know this is not perfect, but this change makes hack like #3679

The patch deallocate the memory in `mrb_default_allocf` but that
hinders GC in `mrb_realloc`.
 2017-05-31 23:01:04 +09:00

 2017-05-26 10:50:51 +09:00
Yukihiro "Matz" Matsumoto 83fc915213 Add new range check macro FIXABLE_FLOAT(); ref #3652

Yukihiro "Matz" Matsumoto 9e40586d43 Add cast to mrb_int in mrb_fixnum() when MRB_WORD_BOXING. 
Without this cast, `long int:63` can cause warnings.
