libstdc++: Fix std::basic_stacktrace special members [PR105031]
The PR points out that there is a non-constant condition used for an
if-constexpr statement, but there are several other problems with the
copy, move and swap members of std::basic_stacktrace.
libstdc++-v3/ChangeLog:
PR libstdc++/105031
* include/std/stacktrace (basic_stacktrace::basic_stacktrace):
Fix allocator usage in constructors.
(basic_stacktrace::operator=(const basic_stacktrace&)): Do not
try to reallocate using const allocator.
(basic_stacktrace::operator=(basic_stacktrace&&)): Fix
if-constexpr with non-constant condition. Do not allocate new
storage if allocator propagates. Do not set _M_size if
allocation fails.
(basic_stacktrace::swap(basic_stacktrace&)): Fix typo. Add
assertion that non-propagating allocators are equal.
* testsuite/19_diagnostics/stacktrace/stacktrace.cc: New test.
