Both following lines produce "1" in ruby versions before 2.4.0, but second one causes Segmentation fault in ruby 2.4.0 and head (ruby 2.5.0dev (2017-03-13 trunk 57944) [x86_64-linux]).
p Thread.new(1){ |x| x.to_s }.value # => "1"
p Thread.new(1, &:to_s).value # Segmentation fault
Output for 2.4.0 (for this and other versions on travis-ci):
[BUG] Segmentation fault at 0x00000000000000
