Glad you found what you needed, but please put that code in code tags..
Also, I see nothing in there that needs C++ libraries or even a C++ compiler, it'll compile as pure C.

So install it. If you're concerned about low-memory, you need swap. You don't even need a partition to add swap, you can just make a big empty file, run mkswap on it, and mount it as swap.

malloc_stats
MALLOC_STATS(3) Linux Programmer's Manual MALLOC_STATS(3)
NAME
malloc_stats - print memory allocation statistics
SYNOPSIS
#include <malloc.h>
void malloc_stats(void);
DESCRIPTION
The malloc_stats() function prints (on standard error) statistics about memory allocated by malloc(3) and related functions. For each
arena (allocation area), this function prints the total amount of memory allocated and the total number of bytes consumed by in-use alloca-
tions. (These two values correspond to the arena and uordblks fields retrieved by mallinfo(3).) In addition, the function prints the sum
of these two statistics for all arenas, and the maximum number of blocks and bytes that were ever simultaneously allocated using mmap(2).
CONFORMING TO
This function is a GNU extension.
NOTES
More detailed information about memory allocations in the main arena can be obtained using mallinfo(3).
