RE: trouble linking with -O and unboxed tuple

With ghc 5.04.2 I'm having some trouble linking (debian linux).

Here's the error I get:

/home/bjpop/woo/lib/buddha-0.5/libbuddha_p.a(Partial.o): In function `s1jZ_fast1': Partial.o(.text+0xa44): undefined reference to `GHCziPrim_zdwZ2H_entry'

Ok, could you help us out by doing the following: compile Partial.o, using exactly the same flags you were using to demonstrate the problem, but add -ddump-simpl -dppr-debug -ddump-stg and send us the output. Also the source for the module would help too. Cheers, Simon
