Daniel Bertalan 78e7ff008b LibC: Fix negation overflow UB in sys/mman.cpp ... When the system calls return `NumericLimits<ptrdiff_t>::min()`, negating the return code would produce `NumericLimits<ptrdiff_t>::max() + 1` since we are on a two's complement architecture. Because this value cannot be stored, signed overflow occurs which is UB. This can be fixed by applying the negation to `EMAXERRNO` since that's known to contain a relatively small value. Found when running tests with Clang.		2021-08-08 10:55:36 +02:00
