C++17 already has the needed helper function: ceil(duration).
So just change all instances of:
__clock_t::now() + __reltime
to
using __dur = typename __clock_t::duration;
__clock_t::now() +

I grep'ed the latest devel source tree (git sha: afadff66) for occurrences of
now\(\). The same bug appears several times in include/experimental/io_context
and include/experimental/timer.

The same incorrect logic that was fixed in bug 68519 is present in the
implementations of future::wait_for and shared_timed_mutex::wait_for. The fix
should be the same: explicitly duration_cast the __rtime

When I compile with -std=c++11 or -std=c++14 and with -O0, I get this undefined

It's easy to overthink this. 0.0 is perfectly acceptable, as is any other
_RealType in the range [0, 1.). But since rounding was, presumably, to-nearest
or up, it's slightly disconcerting that 0.0 is neither

The misbehavior is observable by comparing an rng that is invoked directly with
one that is invoked via generate_canonical.

The single-argument form of shared_ptr::reset fails with a static assertion
when the pointer type is void.

The problem is the string(length, c) constructor on line 255 of string_view.
The begin/end constructor is what's needed. Here's a quick demonstration.

Here's a slightly smaller test case. The problem is the 'movdqa'. According
the x86-64 ABI, rsp+8 is 16-bit aligned at the entry to main, and therefore so
