Please submit a full bug report,
with preprocessed source if appropriate.
This appears to be the same failure as observed on mainline on November.
The patch that fixed this was:
2005-11-24 J"orn Rennecke <joern.rennecke@st.com>
* caller-save.c: (this_insn_sets): Move into:
(save_call_clobbered_regs).
(mark_set_regs): Get this_insn_sets from data.
(save_call_clobbered_regs): Take sets of the return value by
sibcalls into account.

OK to backport to 4.1 if bootstrap on i686-pc-linux-gnu succeeds?
