Title:
FTBFS with GCC 15.2 on riscv64
Status in coreutils package in Ubuntu:
New
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.
