bash: memleak bug fix for builtin command read
Built in command "read" with "-e" use Readline to obtain the line in an interactive shell. In this process, a string "rlbuf" is just allocated without free operation thus cause memory leak. This patch had been submitted to upstream: http://lists.gnu.org/archive/html/bug-bash/2017-02/msg00061.html (From OE-Core rev: a2b278a6eaa9e9b48d858e3be6712267c0122598) Signed-off-by: Zhang Xiao <xiao.zhang@windriver.com> Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
