Hi I'm trying out ghc-4.02 using the linux binary release. GHC dies with the following error message when trying to compile one of my files: ghc-4.02 -fvia-C -fglasgow-exts -O -c TclWidgets.hs hsc: fatal error: evacuate: strange closure type I've tried compiling it without the -O and with -Onot but don't get anywhere. With an earlier module I get the following warning: /tmp/ghc12270.hc:994: warning: `c9h2_closure' was declared `extern' and later `static' /tmp/ghc12270.hc:1063: warning: `c9h5_closure' was declared `extern' and later `static' Any ideas?
