The offending instruction is:

             jra .L186               |

And the table L155 is just too far from the above instruction, so
the displacement is too large, causing the failure.

Looks like a compiler bug to me?

Yes, it's https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104028.

Thanks for the information, we have added the commit 43ca110050
to ignore list to avoid reporting it again.
