I saw some errors from valgrind when it tried to read the libstdc++ debuginfo. I tracked this down to this upstream bug: https://bugs.kde.org/show_bug.cgi?id=278313 Which is fixed in valgrind: r12338 | bart | 2012-01-16 10:11:07 -0700 (Mon, 16 Jan 2012) | 1 line debug info reader: Add support for DW_TAG_unspecified_type. Closes #278313. This is simple and maybe worth a backport.
