I tried building using LTO config `-gdwarf-4 -fomit-frame-pointer -flto -DNDEBUG` (dwarf4 is for callgrind to work), host compiler is clang-18, linker ld.lld. Turns out, 32Gb machine is not sufficient to link the `clang-19` executable, process runs out of memory.
Are there any tricks to make this work?
