Issue #10626 has been updated by Jarosaw Rzesztko.


A still more simple test case for apparently the same problem:

It really isn't simply an unhandled stack overflow. If you decrease the number of allocations, the program runs just fine.

I get a BUS error from executing the following Ruby program: https://gist.github.com/jaroslawr/8579678d7c68a49208f0

I am on Gentoo Linux and Ruby 2.1.5, and have also tried Ruby 2.1.4, 2.1.3,..., down to 2.1.0. My colleagues The problem seems to lie in rapidly consuming stack space, and goes away when the stack size limit is increased with ulimit -s. For the real world context behind this, see the corresponding Rails issue I opened:
