Based on your excellent bug report, I fixed this one yesterday:

I can't reproduce this (on Debian stable). How exactly did you configure 
dovecot sources to use ld.gold? I just installed the binutils-gold 
package, but I get the impression that ld.gold may not actually be used. 
Also, perhaps this is caused by a version difference (mine is GNU gold 
(GNU Binutils for Debian 2.20.1-system.20100303) 1.9).

I get the impression that this is an LD bug, but I do like to be sure.

Stephan.
