Is the release mode link error an actual error, or just (un)informative
messages being printed by the linker. This looks like

   http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16625

which was fixed in gcc 4.1. We saw these same messages when using some
versions of gcc 3.3.x on some distributions, but were never able to
assign any actual problem to anything related to this. That is, so far
as we could tell these messages look scary but may actually be harmless.
