I tried the most recent darcs version of binary, and the problem appears to have been fixed, presumably by the patch replacing inlinePerformIO with unsafePerformIO.

It turns out that, although the code I posted earlier in this thread now works, the larger piece of code which I am actually interested in running does not...

I guess this is the price you pay for using libraries which make use of RULES pragmas and unsafePerformIO and friends.

I'm keen to identify what your problem is, however, Duncan is on vacation, and I'm writing up my dissertation. Possibly Lennart can track this down if its a Data.Binary issue. If its a ByteString issue, Duncan or I can investigate it soonish. However, we'll need a test case, so more info please! :-) Also, the first place to look would be Data.Binary (and also try out the stable branch of Data.ByteString). -- Don
