Program aborts with segmentation fault when profiling used.
I have a program that I have compiled under ghc6.5
(downloaded from the CVS repository on May 5/6), on
Fedora-2 core running on a PC. This will run fine when
compiled without profiling. With profiling enabled
(-prof -auto-all with GHC, and +RTS -p for the
program), it aborts, with the message "internal error:
Segmentation fault".
The same program will compile and run, both with and
without profiling, under ghc6.2.1. I have also tried
with different datasets, and the same pattern occurs.
I updated my ghc installation from CVS today (9th May),
but have not been able to update my ghc installation
to see if this problem has been removed, as the
fptools-level build process is failing, with the
Haddock build complaining that parsec-1.0 is an unknown
package when building Utils.hs; building in the ghc dir
results in a failure to find a module Version when
building Main.hs in the utils/ghc-pkg area.
The program and dataset are contained in the attached
gzip'd tar file. I compile it (without profiling) using
ghc --make -fglasgow-exts -o Reader Reader.hs
