The start of the compilation of dev-lang/rust begins with "Checking for at least 12032 MiB disk space at" I have noticed that this already takes over 14GB to compile. It is worthwhile to update the minimum required disk space to a more accurate value.
Could you provide outputs of `emerge --info` and `emerge -pvq dev-lang/rust`? rust attempts to auto-detect space requirements which can range from 8GB to 30+GB, and if it's wrong in this case need to figure out why

I assume -flto was turned off for rust, right? (I know GentooLTO has an exception for it). Albeit it'd be a likely culprit to use more space. Unsure what impact other flags may have. I'll mark this a duplicate of the older bug, but this information may be useful. *** This bug has been marked as a duplicate of bug 783768 ***
Yes, no LTO, because of GCC 11. I am again surprised that I could not find the duplicate myself.
