解决办法是：

make MALLOC=libc

网上已经有了 解决办法，为什么要加这个呢 ，在README 有这个一段话。

Allocator
---------

Selecting a non-default memory allocator when building Redis is done by setting
the `MALLOC` environment variable. Redis is compiled and linked against libc
malloc by default, with the exception of jemalloc being the default on Linux
systems. This default was picked because jemalloc has proven to have fewer
fragmentation problems than libc malloc.

To force compiling against libc malloc, use:

 % make MALLOC=libc

To compile against jemalloc on Mac OS X systems, use:

 % make MALLOC=jemalloc

而且libc 并不是默认的 分配器， 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。

但是如果你又没有jemalloc 而只有 libc 当然 make 出错。 所以加这么一个参数。
