In some cases we create an illegal Dwarf_Die by clearing all fields. The idea is that dwarf_tag () on such a Dwarf_Die will return DW_TAG_invalid, to indicate that the Dwarf_Die is unusable (and other functions will also return errors). But when "reconstructing" the Dwarf_Die addr we might use the cu before realizing the Dwarf_Die is invalid. Fix this with an explicit NULL check and add a testcase.

The project home is http://elfutils.org/ Releases are published at ftp://sourceware.org/pub/elfutils/ Which can also be found at https://sourceware.org/elfutils/ftp/ To build a release do: ./configure && make && make check Please check the configure summary to make sure all recommended features are enabled. There should be no failures after make check. Please reports bugs at https://sourceware.org/bugzilla/ The current elfutils source code can be checked out with git clone git://sourceware.org/git/elfutils.git To build a git checkout do: autoreconf -i -f && \ ./configure --enable-maintainer-mode && \ make && make check The developer mailinglist to send patches to is elfutils-devel@sourceware.org. https://sourceware.org/ml/elfutils-devel/ To subscribe send an email to elfutils-devel-subscribe@sourceware.org Or use the form at https://sourceware.org/lists.html#ml-requestor See the CONTRIBUTING file for how to propose patches to the code.
