Pretty printer error printing flat map #314
Description
Boost: 1.88.0
GCC: 15.1
In the basic example below that uses unordered_flat_map, and breaking in gdb at the cout, gdb fails to print the contents of the map.
#include <boost/unordered/unordered_flat_map.hpp>
#include <iostream>
int main()
{
boost::unordered_flat_map<int, int> map;
map.emplace(1, 2);
map.emplace(3, 5);
map.emplace(5, 6);
std::cout << map.size() << std::endl;
}
(gdb) print map
$1 = boost::unordered_flat_map with 3 elements = {[5] = 6Python Exception <class 'gdb.error'>: There is no member or method named N.
It seems like gcc might be compiling out the static constexpr member N in the group15 class.
