I have a problem with profiling using a freshly installed GHC 5.04 under Solaris. With the following program crash.lhs:

Please install 5.04.1 instead, I believe this bug was fixed.

Thanks, that indeed solved the problem. Another question: The profiling mode of GHC-4.08.2 did also output (in mode +RTS -p) the time spent on garbage collection (as an additional percentage of overall running time). With the programs I tested so far under GHC-5.04.1, I never saw such an indication in a.out.prof, although for the same programs under GHC-4.08.2 considerable garbage collection times were measured. Does this mean that: a) the indication of garbage collection times has been dropped from profiling reports (can I obtain them in another way?), or b) the newer GHC is so smart that it optimised away the need for garbage collection in the particular (few) programs I tested, but otherwise the GC times will show up in profiling reports, or c) something else?
