Arnd Bergmann <arnd at linaro dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- Version|7.0 |7.0.1 --- Comment #2 from Arnd Bergmann <arnd at linaro dot org> --- I updated to the latest checkout (r244860) and tried again with "arm-linux-gnueabi-gcc-7.0.1 -Wformat -Wformat-signedness" and "x86_64-linux-gcc-7.0.1 -Wformat -Wformat-signedness", which both still have the problem. Note that it only shows up when preprocessing and compiling together, not if you first preprocess and then compile!
