Bug #1659: Segfault with Encoding::Converter.asciicompat_encoding('internal')

• Status: Closed

=begin
When my internal encoding is nil, Encoding::Converter.asciicompat_encoding("internal") causes a segfault on trunk and the latest 1.9.1. If Encoding.default_internal is non-nil, the method behaves correctly.

 $ ruby -e 'Encoding::Converter.asciicompat_encoding("internal")'
 -e:1: [BUG] Segmentation fault
