[U-Boot-Users] hello_world crashes U-Boot

I still need to investigate this further, but figured that a post might 
encourage some suggestions about this interesting issue.

hello_word was built with the default Makefile for the PPC440GX and it 
runs just fine. But when it is modified so that "no" stdio is used and a 
structure init is attempted, it crashed U-Boot (see attachment) when 
hello_world returns.

int hello_world (int argc, char *argv[])
         struct pci_controller thehose = {0};

	return (0);

The interesting part is that when one or more stdio functions is added, 
printf() for example, there is no crash.

I was hoping that someone else might be able to reproduce this crash.

My current U-Boot image has about 8 exported functions in addition to 
the default ones. hello_world was built against this image to insure ABI 

Thanks for any suggestions, Andrew
