mbed-os-5.10.4: mallinfo() seems to return inaccurate information

mallinfo() seems to return inaccurate information. A call to mallinfo() returns the arena as 3928. It is like mallinfo is pointing to another heap and not the global heap./media/uploads/morrisrx/mallinfo.png

I'm running an STM32F767ZI and the heap as reported by mbed_heap_size is 510808 Bytes. I can allocate objects that are hundreds of Kbytes, so this seems reasonable.

What needs to happen to have mallinfo() correctly report the global heap size, usage, etc.?

Thanks
