--- Comment #2 from eracpp <eracpp at eml dot cc> ---
This bug was observed in the following example:
https://gcc.godbolt.org/z/p1VreP
#include <algorithm>
#include <array>
int main()
{
std::array<int, 3> arr;
// Mistake: meant to use std::generate.
std::generate_n(arr.begin(), arr.end(), []{ return 0; });
}
This code successfully compiles (unexpectedly) with GCC due to `size > 0` being
treated as well-formed in the case where the type of second parameter `size` is
deduced to be a pointer type such as `int*`. The contrary behavior is observed
with Clang, as seen in the provided Compiler Explorer link above.
The mistake manifests as an unexpected segmentation fault at runtime, rather
thana compile-time error:
