[ruby-core:42233] [ruby-trunk - Bug #5930] source_location of blocks incorrect

Issue #5930 has been updated by Charlton Wang.


I've verified this behaviour under the following versions:

works: ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-darwin10.4.0]
fails: ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-darwin10.4.0]
works: ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]
works: ruby 1.9.1p243 (2009-07-16 revision 24175) [x86_64-linux]

Similar to bug #2427 but maybe the opposite problem. Newer versions of ruby appear to store the source locations of blocks incorrectly when passed as an argument to a multi-line invocation of a function. Snippet of code below reveals the problem:

-----
def foo(*args, &block)
    p block.source_location
end

foo(1,
    2,
    3) do
end
-----

Under ruby 1.9.1-p243: ["-", 8]

Under ruby 1.9.2-p136 and newer: ["-", 5]

It seems with newer versions of ruby, it reports it based on the line on which the function is called instead of where the actual block is. I believe the old behaviour is actually the correct behaviour.
