Hi all,
I do know now why I have again problems with building openoffice.
It seems that exceptions over shared libraries are broken again in
CURRENT.
Alexander, do you have a idea why this got broken again ?
Attached is your test programm ...
Martin
STABLE:
mb@stable:~/cxxtest$ export LD_LIBRARY_PATH=.
mb@stable:~/cxxtest$ ./arf
calling foo
in baz
foo caught Bax thowing...
returned from foo
CURRENT:
mb@current:~/cxxtest$ export LD_LIBRARY_PATH=.
mb@current:~/cxxtest$ ./arf
abort trap
... The exception is not catched at all ...
