[En-Nut-Discussion] Problem with recent Arm-non-eabi-gcc and libs

[Uwe Bonnes]

Hello,

with recent gcc-arm-none-eabi-10-2020-q4-major and probably the other
2020 release,  multiple problems happen in different incarnations
depending on the link option
- with only nut libc, binaries get substantial bigger
- with nanolib, crashed like this appear:
(gdb) att 1
Attaching to program: /devel/en_apps/cps_stm32/cps_f303/cps_stm32.elf, Remote target

(gdb) bt

#8  0x08008236 in main () at /devel/en_apps/cps_stm32/cps_f303/../cps_stm32.c:153

etc.

Do people have better experiences or hints for me?

Thanks
