Thanks for the information, however mine is previous one:

and also this is on single-core ARM. Interesting...

This could be a problem. I haven't seen any of these in my builds. Does
it happen on the 7.4 branch or only HEAD?

This is on GHC HEAD. However this was not so "standard" testing here, as this was a build which used Ubuntu's provided preliminary LLVM 3.0 packages. I did this in order to test them. So now, I'm back to my own LLVM 3.0 build and building the same GHC tree with this to see if this is the problem caused by interaction with either Ubuntu's LLVM 3.0 packages, or new Ubuntu 11.10 or this is really a bug in HEAD. My bet is on Ubuntu's LLVM 3.0 packages as I guess they built them with GCC and default optimization which is not that good[1].

Anyway, new build is just finishing and full testing takes about 24 hours on this board so I'll send you result during Wednesday probably...

Thanks,
Karel
