Indeed I did not, it still sits waiting patiently in my inbox, due to be

Ok, I understand. I've updated my faust-lv2 and faust-vst sources
accordingly, so that they are in sync with the Faust repo again. I still
need to check the generated plugins, though.
Were there any changes in the C and LLVM back-ends as well? That would
directly affect the Pure-Faust interface and probably a couple of my other
sources.

This really looks like a compiler bug to me. At least the error message is
incomprehensible. And glassHarmonica.dsp appeared to work without a hitch
before.
Thanks,
