GDB backtrace shows a target problem. I'm testing the patch below.

I've confirmed that 4.5 has the same problem and 4.3 doesn't.
In this code, tst r9,r9 is moved to wrong place as if

Ah, I see. Could you please send that patch to libc list?
I'll fix gcc/longlong.h on gcc trunk and 4.4 branch after
the usual tests.

I've tried to see what is going on. fill_slots_from_thread
fills wrongly the delay slot of a conditional jmp insn with
add #-4,r15 where r15 is the stack pointer register for SH.

Your patch looks fine to me and I've tested it with make info dvi pdf
