I'm in a profiling kind of mood (read: am sick of my program taking too long to run), but when I ghc with -prof -auto-all (or -auto or whatever), when I try to run my program it seg faults. I don't want to attach all the code, since it's really long, but I *have* tested profiling on smaller programs and it works fine. (Note that the program crashes regardless of whether I put +RTS -p or not.)
Okay, I've only just toyed with profiling myself, but one observation I've made is that it's not a good idea to mix modules compiled with profiling and modules compiled without. That is, always 'make clean' (i.e. 'rm -f *.o *.hi') before you build with a new set of options. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
