I have never seen that error. Can you see if modifying the above line to read -Wl,-elf2flt="-r -s 65536" instead of -Wl,-elf2flt="-r -s 196608" fixes anything?

Changed packages/duktapetest/Makefile LDFLAGS to '-Wl,-elf2flt="-r -s 65536"', result below:

BTW: trying this at stock "22.04.1 LTS (Jammy Jellyfish)" with gcc-12 as default one

I had CFLAGS="-Wall -O2" in env. Removing it fixes the issue (?!)
