I get a link error building firefox trunk with 4.5 (I've tried with many revisions of mozilla-central). I've encountered the issue with 'GNU ld version 2.18.50.0.9-8.fc10 20080822', the latest release 'GNU ld (GNU Binutils) 2.20', and also the current development version 'GNU ld (GNU Binutils) 2.20.51.20091122'. I filed this here because Mozilla builds fine on a number of different platforms with the same ld using 4.3 (and probably 4.4).
Preprocessed sources via -save-temps on this one invocation of the compiler are not possible here but I've included the full output of -v in an attachment. Please let me know if more info is required.
