Printing colourData in this code:

include <string>

static std::string colourData [] {
        std::string("x"),
        std::string("y")
};

int main() {
}


fails:

Breakpoint 1, main () at ss.cpp:12
12      }
(gdb) p colourData
$1 = {Python Exception <class 'gdb.error'>: There is no member or method named
__short_mask.
, Python Exception <class 'gdb.error'>: There is no member or method named
__short_mask.
}

This is caused by files included in the gdb distribution but originating from
the libc++ project.


gdb-13.1
FreeBSD 13.2
