I found the snippet below inside of /usr/bin/traceroute. It's almost as glibc's malloc(3) stored static, relative memory allocation tables in XML. I'm a total n00b in these matters, so if anyone can shed a light on the matter, I'll be grateful.
<size from="%zu" to="%zu" total="%zu" count="%zu"/> <unsorted from="%zu" to="%zu" total="%zu" count="%zu"/> </sizes> <total type="fast" count="%zu" size="%zu"/> <total type="rest" count="%zu" size="%zu"/> <system type="current" size="%zu"/> <system type="max" size="%zu"/> <aspace type="total" size="%zu"/> <aspace type="mprotect" size="%zu"/> <total type="fast" count="%zu" size="%zu"/> <total type="rest" count="%zu" size="%zu"/> <system type="current" size="%zu"/> <system type="max" size="%zu"/> <aspace type="total" size="%zu"/> <aspace type="mprotect" size="%zu"/> </malloc>
