I can confirm that asm_fast.gc crashes on Aarch64 with gcc 10.2.
asm_fast.gc does work on Aarch64 with gcc 8.3.0, so something
changed between those versions.
For now, please run configure with the --with-llds-base-grade=reg
option, and avoid asm_fast grades when specifying grades directly.
(Note that I'm testing under emulation but that should not matter.)
