Hi all, 

After I solved my problems with the GC, thanks to Brendan, now I'm
having some trouble with the function JS_EvaluateScript. In some cases
it return a invalid value at rval. The following is the code I'm
running to evaluate and to get the returned string:

     rts = JS_EvaluateScript( ctx, obj, Expr, Expr_len, "any", 0,
&rval );
     str = JS_ValueToString( ctx, rval);
     s = JS_GetStringBytes( str );

When Expr is "'This is the value of num '+num", I always get the right
value. But if the expression is just "num" ( to get his value as
string ), there are several times that I get a wrong value. ( num is
defined ).
When I evaluate the two expresion, one after the other, in the first
one I get the correct value, but on the second I get an old value.
I hope somebody could give some ideas where I'm making the mistake.

Best regards


Carlos F.
