I've downloaded linux source code with '$ sudo apt source
linux-image-5.15.0-1021-raspi'
After turn off CONFIG_STRICT_DEVMEM with use of '$ sudo make menuconfig'
Kernel hacking --> Filter dev/mem: 'N'

After tried make but no luck...

This might me an out-of-memory issue. Can you please check the memory
consumption during the compilation?

Maybe you should report this to Ubuntu first since you got GCC from them.

Hi!

First I tried to run make from plain terminal (Without X) in hope then will
remain more memory but it failed again.
After I 'freed' while 'make' runned at background and free memory typicaly was
over cca. 150Mi with plain terminal.
Because I didn't knewn when will it broke I runned 'free' by manually wit some
sec distinct. The result in the .txt file. The last record made after the error
report. The one before last is which was the nearest to the failure at 2-3 secs
before.
I tried to run directly the 'gcc <...>' command in background too but I cannot
'free'-d becouse it throw the fault very quickly.

After I swichted to X and ran SystemMonitor and run the 'gcc <...>' and make a
screenshot. The 'gcc <...>' runned about 10th sec, memory usage still under
100%

Hi!

lz4_decompress.o...

Thanks!
