[kou (Kouhei Sutou)]

ruby -v -e ':class.to_proc.source_location' causes inifinite loop:

% /tmp/local/bin/ruby -v -e ':class.to_proc.source_location'
ruby 2.3.0dev (2015-12-19 trunk 53202) [x86_64-linux]
(never finished)

It's also caused with ruby 2.3.0preview2:

/tmp/local/bin/ruby -v -e ':class.to_proc.source_location'
ruby 2.3.0preview2 (2015-12-11 trunk 53028) [x86_64-linux]
(never finished)

This may be related to Proc#call optimization.
