The minimal example cannot trigger the same issue as it doesn't link to glib (?). So what is the error log for the minimal example? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The extended example on 13.1, compiled with just -g does

so it seems to work for me. Note that the libstdc++ pretty printers are contained in the libstdc++48-devel package, mine is

libstdc++48-devel-4.8.2+r205850-74.1.x86_64

can you check if it works for you with using gdb from the command-line as well?

I can confirm your gdb session. I got the same result. So std::array and std::vector seems to work with pure gdb, but not std::unique_ptr.

I expected to not only get the memory address, but the content of the object lool that the pointer is pointing to. Something like: $2 = std::unique_ptr to lool = {my_i = 0}

Certainly a weakness. I'd have expected (gdb) p *unique_lool to work, but it doesn't :/ -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
