I'm using a fairly current yargarto on a slightly older MacOS. Specific details should be extractable from output.sh. As I understand the distinction between linker sections .data and .bss: - initialised data goes in .data - uninitialised data goes in .bss - data that goes in .bss is not guaranteed to be zero-valued I think that my test shows that this version of gcc is putting: - non-zero valued data in .data - zero-valued data in .bss Do people think that this is a fault?

On microcontrollers, this is typically done by copying over their initial values from flash (again, by the run-time startup code).
Ok; thanks. Time to write more startup code :-)
