a recent snapshot from the 3.3 branch gives

        str     r4, [sp, #-4]!
.LCFI0:
.LM2:
        ldr     r4, .L2
.LBB2:
        umull   r2, ip, r4, r1
        ldr     r1, .L2+4
        ldmia   r1, {r3-r4}
        mov     r1, ip, lsr #3
        adds    r2, r4, r1
        adc     r1, r3, #0
.LM3:
        @ lr needed for prologue
.LM4:
        ldmfd   sp!, {r4}
        b       _ZN9CEventBug4waitEy

So I think this is fixed.  Please can you try the 3.3.1 release.

R.
