BTW, I think this one is proposed to be fixed for 4.2.0.1

Details:
[This changeset revises an earlier one sent to review, fixing an
ugly workaround.
Everything indicated under Tests has been retested with this
revision.]
The implementation of catchFunctionExceptions (catcherrors) was
blind to static functions,
'this' cannot be used in static functions.
To tell that a function is static, this changeset peeks up the
tree to the parent
of the function node, which should be a ASTModifiedDefinition
('moddef'), and checks the static
flag there. A shortcut in copying part of the tree without the
moddef
needed to be fixed, to do that, a 'shallow copy' function was
added to the moddef class.
An alternate way of detecting static-ness is to set a 'static'
property in the options.
I had tried in addressing LPP-5813 (not yet completed), and had
some trouble getting
it to work. It's not clear which one is cleaner, but the one
that works wins for me.
This fix is slightly more encompassing than it needs to be, it
also disables any possibility
of applying the WITH_THIS directive within a static function.
This should always be
correct. Changing that to be narrower did not affect the SWF8
problem.
Tests:
(dhtml,swf8,swf9) x (lzpix,weather,smokecheck,hello) x (enable
catcherrors, disable catcherrors)
