Comment(by simonmar):
I think Roman is right, not copying the arguments is bad because the
caller doesn't know the lifetime requirements for the memory (it is done
this way because historically `hs_init` was called with the real `argv`,
which is statically allocated so it doesn't matter). In retrospect I
should have fixed this in my recent cleanup of `RtsFlags`, but forgot
about this ticket.
If `hs_init` needs to return an error condition rather than aborting, then
we need to define a new API for that, and fix `setupRtsFlags`. I don't
think we need to do this for every case of `stg_exit` and certainly not
for `barf`: these are all internal error conditions and we have no
sensible way to recover.
