i was pinging a host from a windows machine and made a typo which seemed harmless.  the end result was it interpreted my input differently than what I had intended.   thinking this was a m$ issue I quickly took the opportunity to poke fun at windows as the senior m$ admin was near by.

"look at how brain dead this os is,  it can't even do simple math!"

He is now looking at my screen scratching his head…..

"watch,  i'll open a shell on os x and show you how it can add 0 +10"

I open a shell on os x,  same behavior as windows.

" ok so apple is brain dead too,  watch,  it'll work on linux!"

same deal…

long story short,  it does work as expected on all our hardware routing gear.    still not sure what is happening here…
