Dwarf Error: Offset with gcc 8

Postby wurstnase » Wed May 09, 2018 6:42 am

Hi,

I'm building my gcc with bleeding edge script from Freedie Chopin: https://github.com/FreddieChopin/bleedi ... -toolchain

GNU objdump (bleeding-edge-toolchain) 2.30
arm-none-eabi-gcc (bleeding-edge-toolchain) 8.1.0

Normal builds work until I enable LTO with -ggdb.
