Description Mark Wielaard 2010-02-10 09:15:37 EST
+++ This bug was initially created as a clone of Bug #561506 +++

There are two bugs in elfutils libdwfl and libdw cfi reading support which impact finding the call frame address as used by systemtap.

commit ee29a31c48e4b1ec606a311cba0a6328ce8ea448
Author: Mark Wielaard <mjw@redhat.com>
Date:   Tue Feb 2 20:44:53 2010 +0100

    libdw/fde.c (intern_fde): Fix length check for sized_augmentation_data.

commit eacdcf3e86653b97932f3d6e35c9271b3f406369
Author: Mark Wielaard <mjw@redhat.com>
Date:   Tue Feb 2 15:45:24 2010 +0100

    Always set bias in dwfl_module_dwarf_cfi() and dwfl_module_eh_cfi().

The first is hard to work around in systemtap itself. The second could be worked around, but since we need the first fix anyway, it would be nicer to just have both issues resolved at the same time.
