"Simon Marlow"
I can't seem to get the Garbage Collector to work properly on MacOS X. When a program triggers the Garbage Collector, it aborts with the following message: a.out: fatal error: scavenge_stack: weird activation record found on stack: 0
I'd be willing to bet large amounts of money that this is due to the macro LOOKS_LIKE_GHC_INFO() returning the wrong value. Read the comments in ghc/rts/Storage.h, particularly the sections on "Address space layout macros" and "Macros for distinguishing code pointers from data pointers". In the latter section, unregisterised compilation on MacOS X should be using Plan C.
(Sigbjorn - did you already solve this one?)
No, I had to hand back the OS X box I was using. Wolfgang seems to be making great progress on getting a full port going though. --sigbjorn
