--- Comment #1 from ktkachov at gcc dot gnu.org ---
Confirmed.
In the code
538 if (!aarch64_classify_address (&addr, XEXP (x, 0), mode, true))
539 return false;
540
541 unsigned regno = REGNO (addr.base);
542 if (global_regs[regno] || fixed_regs[regno])
543 return false;
addr.base is not guaranteed to be a register. In this instance it's:
(mem/u/c:DI (symbol_ref/u:DI ("*.LC1") [flags 0x2]) [0 S8 A64])
