Bug ID: 115166
Summary: RISC-V: flakey relocation truncated to fit:
R_RISCV_GPREL_I against `.LANCHOR1' in slp_run-2.c
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: ewlu at rivosinc dot com
Target Milestone: ---
Affected target: newlib rv32gcv
Our postcommit ci first saw this error Dec 2023 but it was quickly resolved.

We only recently started to observe it be more and more flakey
