Load problems with conflicting symmetry properties

[jodavies]

If I save an expression such as,

#-
Function f1,f2,f3;
CFunction g;

Global test = g(f1,f2,f3);
.store

Save expr.sav test;
.end

and load it in a file with a conflicting symmetry property for g I get a warning (as one would see with conflicting power restrictions on a symbol, for example) but the load then fails:

Function f1,f2,f3;
CFunction g(cyclesymmetric);

Load expr.sav;
Local ltest = test;

Print +s;
.end

Valgrind reports an invalid read in simp6token, "Making sure that factorized expressions are used properly" which seems a weird place for execution to end up here?

Of course, one can work around this by re-declaring `g' with the desired properties after the load and assign.
