ah, yes, very annoying. I see the crash on MacOS as well.
This might be considered a 8.4 bug, AFAIK part of the point of stubs is 
that extensions that work against 8.3 also do so against 8.4 without 
change. You might be using non-public stub APIs that are not guaranteed 
to stay the same though.

looked at tclMacLoad.c and this doesn't seem to be possible without a 
core change, the fragment name is deduced directly from the package 
name at present...

I've found another way though, I've managed to build from your sources 
without much trouble (you seem to have forgotten to include the project 
however, I reused an older one that I still had).
The solution that I've taken now is to make two shlb's, 
QuickTimeTcl8.3.shlb and QuickTimeTcl8.4.shlb with pkgIndex resources 
that only load if the tcl_version matches. Not perfect (a single file 
would be better), but it works.

an archive with 8.3 & 8.4 QuickTimeTcl binaries, the sources I changed 
and my project is at

I managed to build against CarbonLib with 8.4 after a few minor 
changes, but can't load at present because the work to link Wish 
against CarbonLib hasn't been done (only tclsh). Not sure if this is 
really useful anymore, better to just test on OSX.

not yet, part of the point of the whole discussion about frameworks is 
determining what the most natural package format for MacOSX is...
If you want, I can clone the TclAE project, set it up for QuickTimeTcl 
and pass it along. It doesn't use the framework structure, and so 
doesn't depend on the current discussion/patch.

Cheers,

Daniel
