Comment (by thorkilnaur):
I am no longer able to produce the error message {{{internal error:
stg_ap_p_ret}}} using the method originally described (compiling a program
with GHC HEAD while spending resources in a separate process). I have
looked a bit more into the timeout case: As I read what happens,
timeout.hs is compiled using the stage1 inplace compiler. And:

Please report this as a GHC bug:

So {{{-O2}}} makes a difference.
