Was Lewis running with an XRT/Graph or SciPlot build?

I'm crashing /usr/local/epics/extensions/bin/solaris-sparc/medm, which
I've
verified is built with XRT/Graph.

I also ran MEDM built with SciPlot 
(/APSshare/epics/extensions_2009_07_22/bin/solaris-sparc64-v10-gnu/medm)
, and 
that didn't crash.
