To reproduce:
1) Download the karplus.dsp example from
http://faust.grame.fr/index.php/online-examples.
2) Edit faust2dssi to add -g flag.
3) Build karplus.so with `faust2dssi karplus.dsp` and copy into, say,
~/.dssi.
4) Attempt to load with `jack-dssi-host karplus.so`.
This results in a segfault in std::string::assign. The stack trace:
(gdb) r ./karplus.so
