Hi,
I am using yocto to build my custom distribution targetting arm64 on
Ubuntu 18.04.4.
I have an issue compiling dts which was preprocessed with gcc version
7.5.0 (I haven't tried other version) and '-g3' flag. The error message:
./scripts/dtc/dtc -O dtb -o

Once the '-g3' flag is removed, the part of the preprocessed DTS looks
like this:

And the device compiler succeeds.
Is it a known behaviour?
