Closed

ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
Description
This works:
/ (?<foo>.*)/ =~ "bar" && true
This produces a stack consistency error with 2.4.0 but not with 2.3.3:
/ (?<foo>.*)/ =~ "bar" &&
true
$ irb
2.4.0 :001 > / (?<foo>.*)/ =~ "bar" && true
=> nil
2.4.0 :002 > / (?<foo>.*)/ =~ "bar" &&
2.4.0 :003 > true
