Subject: std::string add nullptr attribute
Date: Thu, 9 Feb 2023 13:26:33 +0000 [thread overview]
Message-ID: <7e6e3bbf-0dac-0632-0e8f-372bd32a6923@jguk.org> (raw)
Hello
Could GCC's STL implementation add nullptr attribute to prevent code like this compiling?
g++ -Wall -o string string.cpp
std::string c(nullptr);
At least GCC STL does reject it at runtime:
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string: construction from null is not valid
Aborted (core dumped)
Note, my code isn't like this, it is just an example to suggest adding the nullptr attribute, as its clearly already rejected at runtime.
Regards
Jonny
