Hi,
I found the immediate cause of this crash. It happens in
ImplFontCharMap::DeReference()
in vcl/source/gdi/metric.cxx.
The reference counter goes to -1 which means that the object is freed with
delete operator twice. And number of calls to AddReference and DeReference does
not match. Debugging why this happens would require some more time.
My CWS osxct01 has a fix already. I'll transplant it into a faster CWS.
I have just found out that it was your code :-) I could save me an hour of work if I read
your mail immediately. Let us see if my fix is the same as yours:
