dearblue 7a0418304e Fix memory leak for string object when out of memory 
The `mrb_str_pool()` function has a path to call `malloc()` twice.

If occurs `NoMemoryError` exception in second `malloc()`,
first `malloc()` pointer is not freed.

dearblue fef1c152ce Fix stack overflow when out of memory 
As a result of this change, no backtrace information is set
for NoMemoryError (`mrb->nomem_err`).

Detailes:

When generating a backtrace, called `mrb_intern_lit()`,
`mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with
`exc_debug_info()` function in `src/error.c`.

If a `NoMemoryError` exception occurs at this time,
the `exc_debug_info()` function will be called again,
and in the same way `NoMemoryError` exception raised will result
in an infinite loop to occurs stack overflow (and SIGSEGV).

dearblue da7d7f881b Fix NULL pointer dereference mrb->nomem_err when not initialized 
Add internal functions (not `static`):

  * `mrb_raise_nomemory()`
  * `mrb_core_init_abort()`

KOBAYASHI Shuji 9f081183d2 Improve compatibility to CRuby for Float#to_s 
Bfore:

  Float::INFINITY.to_s  #=> "inf"
  50.0.to_s             #=> "50"
  1e20.to_s             #=> "1e+20"

After / CRuby:

  Float::INFINITY.to_s  #=> "Infinity"
  50.0.to_s             #=> "50.0"
  1e20.to_s             #=> "1.0e+20"

KOBAYASHI Shuji 68735d1261 Fix dump/load float leteral evaluate to infinity 
Example:

  # example.rb
  p(2e308)
  p(-2e308)

  Good:

    $ bin/mruby example.rb
    inf
    -inf

  Bad:

    $ bin/mrbc example.rb
    $ bin/mruby -b example.mrb
    0
    -0

Cause:

  Float infinity representation is `inf` on dump and it is converted by
  corresponding `String#to_f` on load.

Treatment:

  - Introduce new representations (`i`: +infinity, `I`: -infinity)
  - Allow old representations (`inf`, `-inf`, `infinity`, `-infinity`) too
  - Raise error for unknown representations (use corresponding `Kernel#Float`)

KOBAYASHI Shuji 648b57620a range: Embed edges in RRange on boxing environment. 
[Breaking changes]

Developers must use following APIs for accessing attributes of RRange
because RRange structure depends on boxing setting.

- mrb_range_beg
- mrb_range_end
- mrb_range_excl_p

Yukihiro "Matz" Matsumoto ccc5edc60d Small refactoring of #4188 2018-12-17 16:00:22 +09:00
Yukihiro "Matz" Matsumoto e690314525 Recover #to_int; ref #4177 
We have removed implicit conversion to strings using `to_int`. But some
users still using `to_int` as a typical integer method, i.e. they do
string check by code like: `obj.respond_to?(:to_int)`. So we have
recovered the method.
