Question

Why and how to solve it?

[jstkdng]

you could be running out of ram while building

[playgithub]

you could be running out of ram while building

CPU 8 cores 16 threads RAM 16G

-j 8 failed, it never failed before version 108

[PF4Public]

clang version 14.0.6

You need either clang-15 or a patch. Look here

[playgithub]

As a note, the patch works.
