--- Comment #8 from Theodore.Papadopoulo at inria dot fr ---
Would it be at least possible to make the error clearer ?
Currently, it just gives
In file included from /usr/include/c++/14/string:43,
from test.cpp:1:
/usr/include/c++/14/bits/allocator.h: In function ‘int main()’:
/usr/include/c++/14/bits/allocator.h:193:52: error:
‘std::__cxx11::basic_string<char>(((const char*)"abcdefghijklmnopqrst"),
std::allocator<char>())’ is not a constant expression because it refers to a
result of ‘operator new’
193 | return static_cast<_Tp*>(::operator new(__n));
| ~~~~~~~~~~~~~~^~~~~
Without even the stack leading to that place...
Ideally, mention the SSO optimization and its limits ?
It is very disturbing to have two different behaviors depending only on the
length of the string without a (somewhat) clear explanation.
