When a program crashes, is its memory reclaimed by the OS?

[D'artagnan]

Dynamically allocated (malloc) memory is returned back to the OS when a

program terminates normally. But what if the program crashes? Is its
heap also freed? Thanks.

That depends entirely on the OS. The C++ standard has nothing to say
on the matter -- wrong jurisdiction. However, generally speaking, yes,
most OSes will reclaim all such memory.
