I identified the difference which causes the issue
between bash built from original source and msys2 bash.

If --enable-readline and --with-installed-readline is specified
to configure, the problem causes even with bash built from original
source.

Also, removing --with-installed-readline from configure and removing
READLINE_LDFLAGS= from make in PKGBUILD of MSYS2 bash package solves
the issue.

So it seems to be a readline problem, not a bug in bash itself.
