If the debugger just randomly changes malloc state, it's impossible to
debug memory or pointer issues...

So I don't believe it should use malloc or a different helper. String
arguments can be placed on the stack just like any other arguments
(within a reasonable limit - anything too large could simply be refused
just like a call with 1M arguments).
