I wonder if the compiler configurations (gcc -v) or the options used at

I tested several compilers and with my .config never triggered a

Hi Marc, Oliver,

We use the below cross compiler:

and here is the detail:

$ /home/nfs/0day/gcc-9.3.0-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc -v
Using built-in specs.

Configured with: /tmp/build-crosstools-xh/gcc/gcc-9.3.0/configure --target=arm-linux-gnueabi --enable-targets=all --prefix=/tmp/build-crosstools-xh/cross --enable-languages=c --without-headers --disable-bootstrap --disable-nls --disable-threads --disable-shared --disable-libmudflap --disable-libssp --disable-libgomp --disable-decimal-float --disable-libquadmath --disable-libatomic --disable-libcc1 --disable-libmpx --enable-checking=release
