Hi,

I just tried avr-gcc 12.1.0 on an old project, and got some new warning I can't explain.

The code is:

PORTC &= 0xFE ;  //clear bit 0.

and the warning is:

warning: array subscript 0 is outside array bounds of 'volatile uint8_t[0]' {aka 'volatile unsigned char[]'} [-Warray-bounds]

What is this warning and what array is it referring to?

Presumably from the macro expansion of PORTC?

Can you paste the full command line? Also, can you add -E to the command line and share the output?

Senthil

Thank you!
