Hi! This TU uses exit, but doesn't include <stdlib.h> or <cstdlib> and relies on some other header to include it indirectly, which apparently doesn't happen on reporter's host.
The other <c*> headers aren't guarded either and we rely on a compiler capable of C++11, so maybe we can rely on <cstdlib> being around unconditionally.
