I'm going with trunk.  I suppose I might give it a go on openSUSE as
opposed to Fedora just to see where that gets me.

Well, it goes UnitsCalc::parseNumber() -> Number::floatValue() ->
cln::double_approx().  So I guess the problem is potentially in cln.  But
like I say, I copied the code over almost verbatim to my test app and the
test app runs fine, so I'm pretty sure it's not wrong arguments being
passed.  In fact I'm spitting out debug statements in both the real code
and the test code and the contents of all the variables seem to match
exactly.  Even the type of the expr MathStructure.

Would valgrind be the thing to go with to check for previous memory
corruption?

Thanks,
