--- Comment #1 from JuzheZhong <juzhe.zhong at rivai dot ai> ---
I think it's probably fixed on the trunk by my recent patch:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=923a67f17badcbe6e2b2e5d3570a265443258c8e
If it has been fixed, plz verify it and send a patch with testcase directly.
Thanks.

Confirm it has been fixed now.
Could you send a patch with test pr112813.c ? To avoid future regression.
Thanks.
