From d3b6303a6853f612a56848ee4e59eaa0b0ab9489 Mon Sep 17 00:00:00 2001 From: Zhang Xiao Date: Tue, 21 Feb 2017 11:30:14 +0800 Subject: [PATCH] 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. Fix it.
