ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
[ruby-core:80147]

Description

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
