Hi y'all! With the latest September update to gdb[1] the builtin pretty printers for (at least) unique_ptr no longer work. (gdb) p x $2 = std::unique_ptr<foo> = {get() = {<No data fields>}} Downgrading to gdb 10.2 seems to fix the issue, but I can't figure out what the underlying cause is. It's either because (a) our gcc[2] and gcc-libs packages are out of date since July[3] _and_ GDB does not support pretty printers for the older stdc++ version or (b) there's a bug in gdb 11.1 Testing out the first hypothesis would mean compiling gcc 11.2 from source, which is something I'm not looking forward. Does anyone else have any knowledge that may be relevant to this issue? -- Best regards, Vasi Vilvoiu [1] https://archlinux.org/packages/extra/x86_64/gdb/ [2] https://archlinux.org/packages/core/x86_64/gcc/ [3] https://gcc.gnu.org//gcc-11/
