cpp init & machine check

Hey guys,
I'm really stuck on this constructor function in the cpp-init. For 
some reason Codewarrior keeps giving me machine check exceptions 
during the branch command shown below:

{
003FA35C: 9421FFF0  stwu     SP,-16(SP)
003FA360: 7C0802A6  mflr     r0
003FA364: 90010014  stw      r0,20(SP)
003FA368: 93E1000C  stw      r31,12(SP)
	voidfunctionptr *constructor;

	/*
	 *	call static initializers
	 */
	for (constructor = _ctors; *constructor; constructor++) {
003FA36C: 3C600040  lis      r3,64
003FA370: 3BE35340  addi     r31,r3,21312
003FA374: 48000014  b        __init_cpp+0x28 (0x3fa388)
		(*constructor)();
003FA378: 819F0000  lwz      r12,0(r31)
003FA37C: 7D8903A6  mtctr    r12
003FA380: 4E800421  bctrl               //MACHINE CHECK
	}
003FA384: 3BFF0004  addi     r31,r31,4
003FA388: 801F0000  lwz      r0,0(r31)
003FA38C: 28000000  cmplwi   r0,0x0000
003FA390: 4082FFE8  bne      __init_cpp+0x1c (0x3fa378)  //branch 
to   003FA378

}
003FA394: 83E1000C  lwz      r31,12(SP)
003FA398: 80010014  lwz      r0,20(SP)
003FA39C: 7C0803A6  mtlr     r0
003FA3A0: 38210010  addi     SP,SP,16
003FA3A4: 4E800020  blr

I'm not sure what is the bne instruction for, if anyone can help I 
would really appreciated.
