workaround to usage-after-free

The fix in this patch is not to free the mmacro as it seems it can continue to
be used later. This leads to a small memory leak, but the usage-after-free
condition is removed.

I didn't look more carefully into fixing this piece of code as there is already
a TODO: to fix it ;)

Is this small memory leak acceptable, or should this be fixed another way?
