This sounds like a compiler bug. Can you try adding
"%define _lto_cflags %{nil}"
To the .spec file and see if that gets you over the hump? I've seen one failure
of this nature in my LTO testing and haven't gotten around to producing a
bugreport suitable for upstream (but the affected package has LTO disabled to
keep it from failing its builds). My tester reports that it's never got a clean
control build of libreoffice, so I've never dug into it for any LTO specific
failures.
I added this %define _lto_cflags %{nil} to the top of the libreoffice
.spec file, and compiled it in mock locally.
And it spits out the same GCC crash error message without LTO.
