Symbol encoding changes after defining a method with same name

[y-f-u]

Environment

Provide at least:

• JRuby-9.1.8.0
• OSX, Fedora...

Expected Behavior

a = :something
a.encoding # #<Encoding:US-ASCII>
def something; end
a.encoding # should be #<Encoding:US-ASCII>

Actual Behavior

a = :something
a.encoding # #<Encoding:US-ASCII>
def something; end
a.encoding # it is now #<Encoding:ASCII-8BIT>

Can I also add some comments about reproducing @fevin86 bug
you need to evaluate the return of def, eg puts it

a = :something
a.encoding # #<Encoding:US-ASCII>
puts def something; end
a.encoding # should be #<Encoding:US-ASCII>

the example he posted works if you paste it into irb, because irb evals return value of each line

Should be the same issue as #4564 (fixed in 01cd84d).

@MSNexploder you are right. Will close this
