服务器上的版本是链接了tcmalloc吗

可以问下出现Argument "MSWin32" isn't numeric这个的原因嘛，感觉出在这个地方挺奇怪的

@lorinlee 请问目前只有cpu profiler能用jemalloc，heap不能用对吧？因为tcmalloc有瓶颈，线上服务只考虑用jemalloc

@lorinlee 本地和服务器跑的是同一套代码，都链接了libtcmalloc_and_profiler.so.4，然后我发现还另外链接了libjemalloc.so.2这个库，是因为这个的原因吗（但是本地也链接了这个，却能看heap和contention）

我是将内置服务的代码插入到.a链接的，发现在本地跑heap和contention profiler可以正常使用，但是在服务器上跑就会出现上面的问题
