こういう stack trace になっていて、 debian の libstdc++ のバージョンが /usr/lib/debug に置いてあるやつと そろってないせいかデバッグ情報出ないな… と、バージョンをそろえてみたりしたんだけど、 そもそも /usr/lib/libstdc++.so.6.0.14 に .gnu_debuglink がついてない…

objcopy --add-gnu-debuglink=/usr/lib/debug/libstdc++.so.6.0.14 libstdc++.so.6.0.14

とかでむりやりつけた。

warning: the debug information found in "/usr/lib/debug//usr/lib/libstdc++.so.6.0.14" does not match "/usr/lib/libstdc++.so.6" (CRC mismatch).

うーんどうしたもんか。
