When object files containing LTO sections are linked together with ld -r the linker merges all sections with the same name. The LTO reader cannot deal with this. Currently it will just ignore excessive data behind the first entry for most sections, which leads to all kinds of errors.
I have been working on a patch kit to solve this, this is just a tracking bug for it. -- Summary: ld -r breaks LTO Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: lto AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: andi-gcc at firstfloor dot org GCC host triplet: x86_64-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44992
