Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org
Reporter: i at zhuyi dot fan

Background
==========
I spotted this when building mlir-gccjit on top of commit
73e7f63ffaacf018b1fad331d2369bf891620e97. The relevant change should be
LIBGCCJIT_ABI_32.
The original scene is at:
https://github.com/Lancern/mlir-gccjit/actions/runs/12128538377/job/33815114366?pr=40
In case it get cleared by github (after a long time), I have also attached the
log archive.
