crash on acid3 test

[Martin Koller]

Hi,

looking at bug https://bugs.kde.org/show_bug.cgi?id=271476
I see a crash in kdelibs/kjs/bytecode/machine.cpp.in line 210
in changeDebugContext() where valgrind found a 0-pointer deref.

    if (d == Enter)
        dbg->enterContext(exec, body->sourceId(), body->firstLine(), fn, args);
    else
        dbg->exitContext(exec, body->sourceId(), body->lastLine(), fn);

it seems dbg can be 0 but is not checked here.

Any idea for the correct fix ?
