#1581 trace "all" crashes when the scope of a method is NIL

[jfaucher]

trace "all" crashes when the scope of a method is NIL.
In my working copy (v4.2), I fixed by applying something like that in the methods at risk :

RexxString *scopeName = (scope == TheNilObject ? scope->requestString() : scope->getId());

Thank you for the thorough analysis of the "scope" of the problem :-)

I can't find a simple test scenario for this, other than running external code with ::options trace all and capturing the output .. ideas?

[Rick McGuire]

Set the .error monitor to a object that captures the output (or even just throws it away). This bug is all about trace not crashing the interpreter.

I love the .Error monitor (but never think of it)

Added test with revision [r11616]
