1) I confirm the problem exists on gcc 3.3.2 (release).
2) As per PR 11451, using "-O -fno-if-conversion" produces correct code (still 
using gcc 3.3.2) :

main:
	; PROLOGUE, vars= 0, regs= 1, args= 0, extra= 0
	push lr
	ldi r5,#0	; 0x0
	ld24 r4,#status
	st r5,@(r4)
	ld24 r4,#ca+8
	ldb r4,@(r4)
	ldi r1,#8	; 0x8
	bnez r4,.L52
	ldi r1,#0	; 0x0
.L52:
	ldi r0,#0	; 0x0
	ldi r2,#8	; 0x8
	bl func
	ld24 r4,#status
	ld r0,@(r4)
	; EPILOGUE
	pop lr
	jmp lr

The bug also exists in the gcc 3.0.x branch (verified with 3.0.2 and 3.0.4).
