With bfd everything works, with gold, I get a Segmentation Fault.
(Ubuntu mantic development release)

First broken version is 2.40-2ubuntu5
Last working version is 2.40-2ubuntu4


According to the diff only one powerpc change was added on gold linker
http://launchpadlibrarian.net/664314947/binutils_2.40-2ubuntu4_2.40-2ubuntu5.diff.gz


And its this one
