Hi,
Just getting back to ruby coding and noticed it doesn't seem to clean up
correctly when malloc flag 'C' is enabled.
When ruby process is aborted, like starting "ruby" from cli and pressing ^D it
prints out:
tmy@phobos home $ ruby
ruby(90150) in free(): chunk canary corrupted 0x11c714984000 0x3fd8@0x3fd8
Abort trap
tmy@phobos home $
Here's the backtrace for it.
