Hi Thomas,
I hope vacation did treat you well.
So I've cvs updated to flex 0.5.1 in CVS and the newest py (as of today) .
It is certainly behaving differently, but I am also still getting the
same crash just at a different time.
I've attached a "gem.pd" and a "simple.pd" only with the gem example
will you actually be able to see anything, but the simple example will
not depend on anything. of course my py script is also attached.
So now rather than crashing on the creation arguments PD now crashes on
the "change" message. Actually it also crashes on "reload." to reload
the script. So loading the script the first time does not crash (when
opening the patch) but it does crash when reloading the script. "bang"
and "reset" messages do not crash pd.
Note the below traces were taken from the simple test patch.
I've also changed my classname "array" to curve3d_array to avoid the
possible numarray conflict. Again I've had no crashes on OSX.
Sorry for the pasting of the patches/scripts I'm using X forwarding and
the patches are not on my email machine!
