Hi, there!

Ah, might this be a new scenario for the recent changes in context-unwinding in exception handlers?

I'd like to load OMeta2 package into Squeak 6.0 alpha (version 20582. 64
bit) but I'm having issue with that.

Attempting to load OMeta2.mcm results in
UndefinedObject>>findNextHandlerContextStarting (As result of
#OMeta2Fail). It seems like exception handling mechanism attempts to
access sender but the sender is nil. I tried also to load manually
OMeta2-Preload-hmm.14.mcz (which works), then OMeta2-Postload-hmm12.mcz
but the same error happens.

I recall, in Squeak5.3, this wasn't happening but further errors were
related with Compiler interface. I managed to fix that, by adding
Parser's method to #OMeta2Compiler. Unfortunalely there were even more
of these, which I could not fix.

Is there any way to make it work? The package works fine in Squeak 4.3
but I want to work in newer versions...

PS. The image is fresh, I didn't even use Preference Wizard. My OS is
Windows 8.1 64 bit.
