Summary: Bug in recent PIC16 Snapshots

Initial Comment:
SDCC 2.8.0 does not exhibit this behaviour. Several recent snapshots do. For example, builds 5253 and 5264.

A simple example is:

This works:
void preset_store(unsigned char num) __wparam{
	unsigned int addr = ((unsigned char)num);
	addr <<= 6;
	MIOS_BANKSTICK_WritePage(addr, current_preset);
}

This does not:
void preset_store(unsigned char num) __wparam{
	unsigned int addr = ((unsigned char)num);
	MIOS_BANKSTICK_WritePage((addr << 6), current_preset);
}

The latter code compiles, but the linker returns the following error:

error: multiple sections using address 0

And then exits. I had seen this same error with other code but had not been able to narrow it down like this.

Thanks for your work devs!
