GHC reports internal error: stg_ap_v_ret

On a PPC Mac OS X 10.4 running

while true; do du -k >/dev/null; done

to spend some resources, in about 50% of the cases, a GHC compile using a recent HEAD fails with this report:

$ /Users/thorkilnaur/tn/GHCDarcsRepository/ghc-HEAD-complete-for-pulling-and-copying-20070713_1212/ghc/compiler/stage2/ghc-inplace --make -fforce-recomp -v0 concio001 -o concio001
ghc-6.9.20080203: internal error: stg_ap_v_ret
    (GHC version 6.9.20080203 for powerpc_apple_darwin)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
Abort trap

This reaction does not seem to depend on what is being compiled.

Best regards Thorkil
