Title:
  FTBFS with GCC 15.2 on riscv64

Status in gcc:
  Unknown
Status in coreutils package in Ubuntu:
  Confirmed
Status in gcc-15 package in Ubuntu:
  Incomplete

Bug description:
  The issue surfaced when uploading coreutils_9.5-1ubuntu3 (LP:
  #2115274).

  A build passed in @waveform's PPA on riscv64 questing-proposed (using
  gcc-15.1), but now we seem to have GCC 15.2 in questing-proposed,
  which crashes while trying to compile coreutils on riscv64.

  The error seems to be related to raising the riscv64 ISA baseline. It
  is yet unclear to me, if this is a GCC error. If a short term solution
  is needed, setting -march=rv64imafdc_zicsr_zifencei for riscv64 should
  work around this issue.
