commit 79fa567e234585dc6a71f9bd069101c993513f3e
Author: Jonathan Wakely <jwakely@redhat.com>
Date: Thu Apr 22 15:46:51 2021 +0100
libstdc++: Reject std::make_shared<T[]> [PR 99006]
Prior to C++20 it should be ill-formed to use std::make_shared with an
array type (and we don't support the C++20 feature to make it valid yet
anyway).
libstdc++-v3/ChangeLog:
PR libstdc++/99006
* include/bits/shared_ptr.h (allocate_shared): Assert that _Tp
is not an array type.
* include/bits/shared_ptr_base.h (__allocate_shared): Likewise.
* testsuite/20_util/shared_ptr/creation/99006.cc: New test.

From b005000525ab0a5116d21217c41fb1da5bd03796 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libstdc++: Fix deserialization for std::normal_distribution
[PR105502]
This fixes a regression in std::normal_distribution deserialization that
caused the object to be left unchanged if the __state_avail value read
from the stream was false.
libstdc++-v3/ChangeLog:
PR libstdc++/105502
* include/bits/random.tcc
(operator>>(basic_istream<C,T>&, normal_distribution<R>&)):
Update state when __state_avail is false.
* testsuite/26_numerics/random/normal_distribution/operators/serialize.cc:
Check that deserialized object equals serialized one.
(cherry picked from commit 909ef4e2727ddc50a32d6ad379a1f1ccc1043c6a)

libstdc++: Initialize std::normal_distribution::_M_saved [PR 99536]
This avoids a false positive -Wmaybe-uninitialized warning, by
initializing _M_saved on construction.

* include/bits/random.h (normal_distribution): Use
default-initializer for _M_saved and _M_saved_available.
