I believe this could be a dup of #28980, so fixed by

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=439385561588f12c1df670aaa92af9babd98f2ac

Do you have this commit in your GDB build? If not, can you try with it?

No, I am using stable ubuntu build of GDB, any place to downloading it for
ubuntu?
Or I may need build it by myself.

>From your log ("gdb-12.0.90"), it seems like you are using a build that is a
preview release of GDB 12, not a stable release build.

If you want to build the latest version of the GDB 12 branch yourself, the
easiest way is to get the gdb-12-branch git branch:
