Thanks!
I receive:

newlib/libc/stdlib/mstats.c:117: undefined reference to `_malloc_stats_r'
newlib/libc/stdlib/mstats.c:145: undefined reference to `_malloc_stats_r'

It seems _malloc_stats_r should be provided by system. But I use pure 
arm-elf-gdb's simulator. Is there some way to provide _malloc_stats_r 
when using simulator with no any underlying OS?

Are there any other approaches to get Heap size exist?
