--- Comment #28 from Daniel Micay <danielmicay at gmail dot com> --- I got jemalloc / Bionic libc (Android) to report errors for malloc and mmap/mremap larger than PTRDIFF_MAX a while ago (along with fixing a missing case for mremap in musl), but glibc needs to be convinced to do the same. It would be a lot easier to convince them with this officially documented. I think it's perfectly reasonable if it's clearly stated that objects larger than PTRDIFF_MAX are not supported and that the libc implementation needs to deal with it.
