Do you have access to an AMD64 machine? I pulled from yhc-devel and the build broke in the same place. This time the offending definition and declaration were: IntegerNode* decodeFloat64(Float64 f, Int32* exp); IntegerNode* decodeFloat64(Float64 f, Int* rExp) The patches attached.

Hi Michał ,

We're still working on fixing your bug, but you might be interested to know there is now a yhc mailing list: http://haskell.org/mailman/listinfo/yhc

If its still breaking in another week start prodding at that list!

Thanks

Neil

Hello,

I would like to report a bug of YHC. Here is the description.

What I did: 1) darcs get http://www.cs.york.ac.uk/fp/darcs/yhc 2) chmod u+x configure; ./configure 3) make 4) The build broke, so I made a change that is attached and finished the build. 5) I compiled using yhc a hello world module (main = putStrLn "Hello") 6) and tried to run it with yhi and received a segv. 7) After changing the runtime Makefile I compiled it with -g and got this stack trace: Starting program: /home/michal/prg/haskell/yhc/inst/bin/yhi Main

Program received signal SIGSEGV, Segmentation fault. 0x000000000040ab10 in run (top=0x2aaaab1c60b0) at mutator.c:79 79 Switch (gdb) bt #0 0x000000000040ab10 in run (top=0x2aaaab1c60b0) at mutator.c:79 #1 0x00000000004041f7 in main (argc=2, argv=0x7fffffa132f8) at main.c:113

I also got a segfault with the devel branch, but wasn't able to compile it with -g. And it broke when building libraries.

Let me know if you need more information.

Thanks, Michal
