If occurs `NoMemoryError` exception in second `malloc()`, first `malloc()` pointer is not freed. commitfef1c152ceAuthor: dearblue <dearblue@users.noreply.github.com> Date: Sat Jan 19 13:05:09 2019 +0900 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). commitda7d7f881bAuthor: dearblue <dearblue@users.noreply.github.com> Date: Sun Jan 20 12:00:38 2019 +0900 Fix NULL pointer dereference `mrb->nomem_err` when not initialized Add internal functions (not `static`): * `mrb_raise_nomemory()` * `mrb_core_init_abort()`
What is mruby
mruby is the lightweight implementation of the Ruby language complying to (part of) the ISO standard. Its syntax is Ruby 2.x compatible.
mruby can be linked and embedded within your application. We provide the interpreter program "mruby" and the interactive mruby shell "mirb" as examples. You can also compile Ruby programs into compiled byte code using the mruby compiler "mrbc". All those tools reside in the "bin" directory. "mrbc" is also able to generate compiled byte code in a C source file, see the "mrbtest" program under the "test" directory for an example.
This achievement was sponsored by the Regional Innovation Creation R&D Programs of the Ministry of Economy, Trade and Industry of Japan.
How to get mruby
The stable version 2.1.1 of mruby can be downloaded via the following URL: https://github.com/mruby/mruby/archive/2.1.1.zip
The latest development version of mruby can be downloaded via the following URL: https://github.com/mruby/mruby/zipball/master
The trunk of the mruby source tree can be checked out with the following command:
$ git clone https://github.com/mruby/mruby.git
You can also install and compile mruby using ruby-install, ruby-build or rvm.
mruby home-page
The URL of the mruby home-page is: https://mruby.org.
Mailing list
We don't have a mailing list, but you can use GitHub issues.
How to compile and install (mruby and gems)
See the compile.md file.
Running Tests
To run the tests, execute the following from the project's root directory.
$ rake test
Note: bison bundled with MacOS is too old to compile mruby.
Try brew install bison and follow the instuction shown to update
the $PATH to compile mruby.
Building documentation
There are two sets of documentation in mruby: the mruby API (generated by yard) and C API (Doxygen)
To build both of them, simply go
rake doc
You can also view them in your browser
rake view_api
rake view_capi
How to customize mruby (mrbgems)
mruby contains a package manager called mrbgems. To create extensions in C and/or Ruby you should create a GEM. For a documentation of how to use mrbgems consult the file mrbgems.md. For example code of how to use mrbgems look into the folder examples/mrbgems/.

Note for License
mruby has chosen a MIT License due to its permissive license allowing developers to target various environments such as embedded systems. However, the license requires the display of the copyright notice and license information in manuals for instance. Doing so for big projects can be complicated or troublesome. This is why mruby has decided to display "mruby developers" as the copyright name to make it simple conventionally. In the future, mruby might ask you to distribute your new code (that you will commit,) under the MIT License as a member of "mruby developers" but contributors will keep their copyright. (We did not intend for contributors to transfer or waive their copyrights, Actual copyright holder name (contributors) will be listed in the AUTHORS file.)
Please ask us if you want to distribute your code under another license.
How to Contribute
See the contribution guidelines, and then send a pull request to http://github.com/mruby/mruby. We consider you have granted non-exclusive right to your contributed code under MIT license. If you want to be named as one of mruby developers, please include an update to the AUTHORS file in your pull request.
