--- Comment #1 from Yao Qi <qiyao at gcc dot gnu.org> ---
Both native testing and remote testing are running on the same aarch64 board,
but the generated corefile is different,

On native, the file is large, and has more sections,
$ ls ./testsuite/gdb.base/non-shared-anon.gcore -lh

Core file:
   
`/home/yaoqi01/SourceCode/gnu/build-gdb/gdb/./testsuite/gdb.base/non-shared-anon.gcore',
file type elf64-littleaarch64.

However, on remote testing, the corefile is small and only has one "load*"
section.
