Before making any changes I decided to see if CVS had been updated in the
meantime, and indeed it had. Thanks! But I noticed some funny parameter
values, and tracked it down to writeFloat_be in
headers/lang/ReadWriteMacros.h. There's a preprocessor check if BIG_ENDIAN
is defined, which it is, so floats get written in native byte order. This
can't be right can it?
The file format for synthdefs is supposed to be big endian. So scsynth
is doing it right.
The problem I'd guess is that SClang file routines write native endian.

Hi list, first post :)
I find that scsynth segfaults within GraphDef_Read, due to what looks
like reading beyond the input buffer. What's the cause of this, I'm not
really intimate with the code yet, but it looks like variables are
being read in big endian order? I'm on x86, so could be a likely
explanation. Anyway, this is the source of the problem with synth
definitions right (having to delete synthdefs/*)? From what I can see
there exists functions for reading bytes in little endian order, how
come these aren't being used?
