I recently emerged dev-python/bsddb3 and then re-emerged my system python with an unset berkdb flag (to avoid the post install deprecated warnings and prepare for the future). In an attempt to resolve an issue with etc-proposals (a seperate bug report) I ran python-updater (even though there was no python version change). python-updater threw a bunch of lines about corrupt ELF symbols: # python-updater * Starting Python Updater... * Main active version of Python: 2.7 * Active version of Python 2: 2.7 * Active version of Python 3: 3.2 * Globally supported Python ABIs in installed repositories: * gentoo: 2.4 2.5 2.6 2.7 3.1 3.2 2.5-jython 2.7-pypy-1.7 2.7-pypy-1.8 * x-portage: 2.4 2.5 2.6 2.7 3.1 3.2 2.5-jython 2.7-pypy-1.7 2.7-pypy-1.8 scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsaproc.debuginfo: corrupt ELF symbols scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsaproc.debuginfo: corrupt ELF symbols scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsaproc.debuginfo: corrupt ELF symbols scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsaproc.debuginfo: corrupt ELF symbols scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsaproc.debuginfo: corrupt ELF symbols scanelf: scanelf_file_sym(): /usr/lib64/icedtea7/jre/lib/amd64/libsapr ................................ ...........

I also rebuilt pax-utils which made no diffrerence. Please note that a nearly identical gentoo box (without the unset python berkdb flag) produces the same warnings if I run python-updater. I note that things on both boxes run OK in most other respects. I am not sure if the problem is related to icedtea, python-updater, pax-utils, something in my system setup, something else, or not really a problem at all.

Reproduce: 1. run python-updater 2. 3. Actual Results: get scanelf warnings as above Expected Results: No corrupt ELF symbols
not sure if there is a way to have scanelf detect & ignore split-debug files. they are generally "corrupt" because they only contain the debug stuff and while the headers refer to the right places [in the original ELF], in the split-debug file, the references point nowhere.
the next release should skip over debuginfo files gracefully http://sources.gentoo.org/gentoo-projects/pax-utils/scanelf.c?r1=1.243&r2=1.244
Future releases of icedtea should no longer strip themselves. Leaving stripping / splitting to the PM should fix this for us as well. http://icedtea.classpath.org/hg/icedtea7/rev/f427c1c7d29c
