[Sugar-devel] Fw: Sugar on a Stick - and OLPCsound

[Art Hunkins]

A bit more info related to my SoaS problem:

The Csound performance files (.csd) run fine from the terminal as they do on 
the OLPC. This would seem to eliminate my .csd as the cause.

Also, the seemingly identical libsndfile-1.0.17 is used by both OLPC and 
SoaS (but note that there further extensions, as mentioned below, *may* be 
different).

Final observation: the run log for Sugar is quite long on the OLPC. The fact 
that my SoaS log is only a few lines suggests that whatever causes the crash 
happens very early in the script - perhaps during initial imports.

Thanks for all help -
