Normally if you add "-v" to the gcc command line, you will get the linker
command line displayed and you can use that to help isolate the problem. 
(Possibly adding "--save-temps" as well).  With LTO however things get rather
messy.

Given that this problem does only occur when LTO is being used, the obvious
suspect is the lto plugin itself.  So you may get some useful output by
adding "-Wl,-plugin-opt=-debug" to command line.   

Cheers

PS.  Which versions of gcc and the binutils are you using ?
