Dear GHC-Users, I am currently developing part of the EdComb library (http://ist.unibw-muenchen.de/EdComb/). I have compiled all files with the -prof and the -auto-all flag. When starting the program * without any RTS options -> everything is OK * with +RTS -p -> everything is OK * with +RTS -h -> fatal error: heapCensus I am using GHC version 4.08.1 on a Debian/GNU Linux Box, installed with the newest Debian packages from http://www-i2.informatik.rwth-aachen.de/Software/Haskell/debian.
