Thanks for the report. Adding Andy  who had attempted to fix this [1]

make allmodconfig ARCH=arm  actually sets CONFIG_FRAME_WARN=2048. But, I 
can see the warning when I change it to 1280 manually (bit strange as I 
expected 1280 to be default based on definition in lib/Kconfig.debug)

I am not seeing any recent code change to this file in at least 6 weeks 
(the changes are still minor code cleanup and nothing before that for 2 
years). I can only assume newer gcc is exposing something here?


Andy,

Wondering if you plan to work on your patches further, anytime soon?

Yes, I am about to read again the threads and compare my latest local version
with that. After additional checks I'll send a v3.
