Bug #16641: Backport request: MJIT crashes on a certain flow of branches
https://bugs.ruby-lang.org/issues/16641#change-84324
* Author: k0kubun (Takashi Kokubun)
* Status: Open
* Priority: Normal
* ruby -v: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]
* Backport: 2.5: DONTNEED, 2.6: REQUIRED, 2.7: DONE
----------------------------------------
## Problem
~~~ruby
def a(b)
".#{b unless b == 1}" if true
end
print(a(0))
~~~
This script `test.rb` crashes by `ruby --disable-gems --jit-verbose=1 --jit-min-calls=1 --jit-wait test.rb`.
## Patch
I fixed this in commit:c4794ed73ad348a61a7cfbe3da0a7eb49ba46eb9, which needs to be backported to 2.6 and 2.7.
