--- Comment #20 from alexey at feldgendler dot ru 2010-09-02 15:13 --- Indeed, when gcc is configured with --disable-gnu-unique-object, the bug doesn't occur. binutils 2.20.1-12 from Debian. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45496

--- Comment #21 from rguenth at gcc dot gnu dot org 2010-09-02 15:23 --- Last guess in the wild is that libelf0 (from libelf) doesn't handle the object file like it should and we somehow silently treat it as an empty one. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45496

--- Comment #23 from alexey at feldgendler dot ru 2010-09-02 15:55 --- Yes, the patch fixes the observed bug. Thanks a lot! However, there's also the issue of missing error reporting for a failure to read ELF. I don't know if it should be fixed as part of this bug or separately. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45496
