Summary0000118: DynamFunc Runtime error: index out of range Bug
DescriptionIn further exploring the IF-statement bug, I find that if I define an anonymous function prior to the DynamFunc, I get a "Runtime error: index out of range" error.
Steps To ReproduceToss the following code into workbench and step through. When it hits f(2) the error is thrown:

#include <tads.h>
#include <dynfunc.h>

 * The main entrypoint - the T3 virtual machine calls this function to
 * start the program running. 'args' is a list of strings giving the
 * command-line arguments that the user specified, if any.
    local str = 'function(val) { if (val > 3) cnt++; }';
    local cnt = 0;
    local g = new function(val)
        if (val > 3)
    //local f = new DynamicFunc('function(val) { val > 3 ? ++cnt : nil ; }', nil, frame);
    local frame = t3GetStackTrace(1, T3GetStackDesc).frameDesc_;
    local f = new DynamicFunc(str, nil, frame);
    //local f = new DynamicFunc('function(val) { if (val > 3) {++cnt;} }', nil, frame);
Additional InformationWindows 7 being run on Mac OS X Lion through Parallels Desktop.

Fixed for the next update.

(This was a problem in the code generator - it was writing the stack frame index instead of the context object index for a local in a context object, which is triggered when the local is accessed from an anonymous function.)
