[MacRuby-devel] unrecognised defined?

[Laurent Sansonetti]

Hi Ben,

This is a missing feature in the compiler, in the way we compile the  
defined? expression.

It's easily reproducible here:

$ ./miniruby -e 'p (defined? FOO && 42)'
unrecognized defined? arg: 21 (NODE_AND)Abort trap

I filed a test_vm case.

Now, it looks like the code you found this problem is bugged.

	if defined? RUBY_ENGINE && RUBY_ENGINE == 'jruby'

should probably be written as

	if (defined? RUBY_ENGINE) && RUBY_ENGINE == 'jruby'

otherwise, it seems to be the equivalent of

	if defined?(RUBY_ENGINE && RUBY_ENGINE == 'jruby')

which is probably not what the code wants to do.
