Comment(by foobum at gmail.com):

 Hmm, this does look like a gcc bug specific to your version; neither gcc
 3.4.4, 4.1.1 or 4.2.4 do this for me. We only use 5 (of 8) regs from
 GENERAL_REGS and we could use less but at the cost of additional insns.
 Using -fomit-frame-pointer should help. The attached patch avoids using
 REG_c explicitly in case that helps too..
