i tried to run the examples: https://github.com/enzienaudio/examples/tree/master/javascript

http://libpd.handmadeproductions.de/
http://libpd2.handmadeproductions.de/

the chip example works fine, but the sampleplayer gives me this error message when i start to play the sample:

warning: a problem occurred in builtin C++ name demangling; build with  -s DEMANGLE_SUPPORT=1  to link in libcxxabi demangling
