Mipsel平台valgrind使用，内存泄漏检测不出来！！！

cyg19860205 2017-12-09 04:09:40

版本 valgrind3.13.0
mipsel 32 位小端模式
Ubuntu 16.04 虚拟机 64位
交叉编译工具链 /opt/toolchain-3.4.x/bin/mipsel-linux-uclibc-

交叉编译步骤：
1、./autogen.sh
2、./configure --host=mipsel-linux-gnu CFLAGS="-mips32r2" CC=/opt/toolchain-3.4.x/bin/mipsel-linux-uclibc-gcc CXX=/opt/toolchain-3.4.x/bin/mipsel-linux-uclibc-c++ --program-prefix=mipsel-linux-uclibc- --prefix=/opt/home/valgrind
3、make
4、make install

将/opt/home/valgrind目录全部移到开发板/opt/home/下

测试程序：
编写测试程序malloc（128），不释放退出。

在PC上用valgrind测试运行，结果显示有128字节的泄漏

用/opt/toolchain-3.4.x/bin/mipsel-linux-uclibc-gcc编译测试程序，在开发板上用mipsel-linux-uclibc-valgrind运行程序，显示

128字节内存泄漏显示不出来，只是显示内存写错误。
