It is difficult to say what is wrong without a lot more info.  You will 
have to try spending some time debugging this yourself.  You can use -da 
to get RTL dumps, and then look at the .greg file.  It will contain info 
on the reloads that were generated by reload.  From this info, you may 
be able to figure out why reload was generating this bad insn.

It may be the case that there is no way to prevent this from happening. 
  You can make this work by defining SECONDARY_RELOADS, and a 
reload_outqi pattern.  See the docs, and see also the early alpha 
targets (! TARGET_BWX) which have a similar problem, no QImode support 
at all.
