I haven't tried all the 6.2.*. Only some of the earliest, and some of

And also v6.1.12. Which is arch latest v6.1.*, doesn't it? I got what
looks to me a similar issue with v6.1.7, if I remember correctly. As of
v6.2.7 and v6.2.9, I get:

After it stalled for a long time at line #19291, or at line #19292, I
interrupted it, ^c, manually. I forgot to look at the resource usage
before interrupting v6.2.9 build. For some of the prevoius versions it
happend, I saw the LD proccess consumed almost all of the machine free
memory. And also a lot of swap. Which happend right at the LD
operation, not before. It is only a desktop, Only 4G RAM.
Have you modified the config at all? If you have, seeing the modified
config would be helpful.
A very sure way to use a lot of memory (well over 4G) at linking is if
you have enabled LTO in the kernel config. Perhaps this is the culprit?
