Public bug reported: == Comment: #0 - Andreas Arnez <ar...@de.ibm.com> - 2016-04-01 12:23:20 == It seems that some Ubuntu debug packages are built with compressed debug info, which is not supported by Valgrind. In particular I've seen that this even applies to the dynamic loader (when libc6-dbg is installed):
