Description Mark Wielaard 2013-09-24 14:58:16 UTC 
Because of a bug in elfutils libdw dwarf_getfuncs() systemtap could miss some probes in C++ programs with DWZ compressed debug files.

A fix exist for upstream elfutils, current git:

https://git.fedorahosted.org/cgit/elfutils.git/commit/?id=1b734df17fca9f89a887b85ffe74616a87388f51

There is also a workaround created for systemtap (not yet integrated upstream):
https://lists.fedorahosted.org/pipermail/elfutils-devel/2013-September/003251.html

It would be good to get this fixed either by a elfutils rebase (if there is an upstream release soon) or by a patch like the above to systemtap.
