Created attachment 894488 [details] build.log While compiling a new i586 system I have found it seems to no long be able to compile clang-18.1.6 with -flto enable as it leads to an memory exhausted error. I'm using a faster amd64 machine for the compile in a chroot, testing the following: -flto -j32 - fail -flto -j1 - fail -flto -Wl,--no-keep-memory -Wl,--reduce-memory-overheads -j1 - fail No -flto and -j32 - Pass Further testing is required to see if this issue exists while compiling clang with itself as it has been known RAM usage has increased since -fno-lifetime-dse was added to clang when being compiled with GCC.
