Bug #10164
closedReproducable segfault for 2.1
Description
Hi,
I have a snippet of code that crashes Ruby 2.1.{1,2} every time for me.
class Exception
def set_backtrace_with_extension
set_backtrace_without_extension(*args)
end
alias set_backtrace_without_extension set_backtrace
alias set_backtrace set_backtrace_with_extension
end
raise

It gives me the following on OSX with Ruby 2.1.2:

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

fish: Job 1, 'ruby die_ruby.rb' terminated by signal SIGABRT (Abort)
For the Ubuntu precise/Ruby 2.1.1 output, check out this link: https://gist.github.com/gsamokovarov/f2dc3b26857b134c8b21. Its pretty big, so I don't feel like pasting it here will help.
Notice how I don't declare the variadic args in the set_backtrace_with_extension method? The other rubies I tested (1.9.3-448 and 2.0.0-p353) give me:
die_ruby.rb:10: stack level too deep (SystemStackError)

I can reproduce only 2.1.2.
