Comment:

 Sadly this patch does not fix this issue, so more work is needed. The
 regression test is this:

 {{{
 main = do
     putStrLn $ "ByteString regression test: "++show (B.empty)
 }}}

 The program dies with this appearing in the runtime console:

 {{{
 dyld: vm_protect(0x00001000, 0x0042D000, false, 0x07) failed, result=2 for
 segment __TEXT in /var/mobile/Applications/38E8C4C6-DA4E-
 4FBA-8183-6473AAA58A66F/Pear.app/Pear
 }}}
