The easiest is using `LD_PRELOAD` to overwrite `malloc/free` with the functions of a shared library like libtcmalloc.so. If LD_PRELOAD can't be used you can specify a command prefix to somehow load and use your allocator. This command prefix is used for different versions of glibc. The command is prefixed with the loader of the glibc version to test. *Note that the whole glibc is changed maybe tampering with the results*. Additionally binary suffixes are -supported.
