Hello,
Using GHC 6.5 from darcs repo ("pulled" in 19/Jun), the following snippet of code seems to cause illegal instruction error on the generated code. The error disappears if I use the Dummy instance on top of Refeable. The code is from my bindings to Judy library, revision 10752 in subversion. http://svn.openfoundry.org/pugs/third-party/HsJudy/ http://svn.openfoundry.org/pugs/third-party/judy/ # original C lib code
To test it you'll need to compile (./configure; make # but not necessarily install) the original library in third-party/judy/Judy-1.0.3. Back in HsJudy, change the Makefile to static link option.
HsJudy$ make testmap HsJudy$ ./testmap
Sorry, I tried to come up with an simpler instance of the problem but didn't found one. The program depend on WordPtr which isn't available in GHC 6.4.2, so I couldn't test it in stable version. It was tested on my amd64, linux 2.6.16 and in audreyt's machine (OSX I think).
I tried to reproduce this without success. I grabbed judy and HsJudy as above using SVN, with -r 10752. Running testmap on x86_64 using last night's GHC build gives me: ~/scratch/HsJudy > ./testmap # Map tests: elems: (NEW on 0x00002ae76b178010) ok simple: (NEW on 0x00002ae76b178100) ok delete: (NEW on 0x00002ae76b178160) ok overwrite: (NEW on 0x00002ae76b178220) ok member: (NEW on 0x00002ae76b1782b0) ok elems: (NEW on 0x00002ae76b178358) ok keys: (NEW on 0x00002ae76b178448) ok int-key map: (NEW on 0x00002ae76b1785b0) ok What did I do wrong? I did have to modify the Makefile a bit to tell it where to find Judy.h, since I don't have Judy installed here. Cheers, Simon
