SEGV caused by Encoding.compatible? "abc", :abc
Calling Encoding.compatible? with a String and Symbol causes a SEGV.
Calling with two Symbols, a Symbol and Regexp, or a String and Regexp works fine.
sasha:source brian$ ruby -v -e 'p Encoding.compatible? "abc", :abc'

The following also causes a SEGV:
ruby -v -e 'sym = "\xff".force_encoding("binary").to_sym; p Encoding.compatible? sym, :abc'
Normally, two Symbols works. The trigger appears to be the symbol not being ASCII only. The following works:
ruby -v -e 'sym = "\x7f".force_encoding("binary").to_sym; p Encoding.compatible? sym, :abc'
