are there known problems with ghc-6.4.* and gcc-4.*? It seems that -O2 does not work (on i386), as gcc says something like "Prologue junk". (Suse linux 10.0 comes with gcc-4.?`as default compiler). -- -- Johannes Waldmann -- Tel/Fax (0341) 3076 6479/80 -- ---- http://www.imn.htwk-leipzig.de/~waldmann/ -------

There may well be problems, yes. Have you tried 6.4.1? Or a STABLE snapshot? Cheers, Simon
Here's the error message (i386, ghc-6.4, gcc-4.0.?

Did not help, I get the same behaviour with ghc-6.4.2.20060121-i386-unknown-linux -- -- Johannes Waldmann -- Tel/Fax (0341) 3076 6479/80 -- ---- http://www.imn.htwk-leipzig.de/~waldmann/ -------

Can you run the offending command with -keep-raw-s-file, and send me the resulting .raw_s, please? Cheers, Simon
