the building of nhc98-1.02 with ghc-5.00 aborts with the message:

Main.hs:8: Failed to find interface decl for `PrelGHC.(#,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,#)' from module `PrelGHC'

Any hints for interpretation?

Workaround: compile this particular module without -O, or with -fno-cpr. Cheers, Simon
