Maybe your stress tests need to be a = little less stressful :-) The build machine does not run out of memory (it has 30-40GB free). $ x86_64-linux-gnu-gcc --version x86_64-linux-gnu-gcc (Debian 13.2.0-7) 13.2.0 $ x86_64-linux-gnu-ld --version GNU ld (GNU Binutils for Debian) 2.41 I have applied the following patch for today.
