Gcc-4.8.2 compiles Calligra 2.7.91 with the same CFLAGS.

The ICE is usually a sign of mismatched compiler versions of LTO objects.  I
cannot reproduce the ICE (but I have to remove -Wl,--no-undefined and the libs
as I don't have them).

Please make sure the libraries do not have LTO bytecode (any of them is
static?)

Thank you.

sci-libs/vc was build with gcc 4.9 lto a few svn revisions before, other
libraries are not built with LTO at all.

I will try vc first and then this again.

No, it was not gcc 4.9 lto on vc, it was gcc 4.8.2 lto, so no slim.

I can't build vc with gcc 4.9 lto:

(In reply to David Kredba from comment #3)
 Thank you.
 
 sci-libs/vc was build with gcc 4.9 lto a few svn revisions before, other
 libraries are not built with LTO at all.
 
 I will try vc first and then this again.

Mixing LTO bytecode from different releases (or even different SVN revisions)
isn't supported and in most cases doesn't work (in surprising ways).

Unfortunately GCC doesn't have good measures to defend itself from LTO
bytecode format changes ... :/

It was the vc with gcc 4.8.2 lto.

Thank you.

I still can't compile calligra with gcc-4.9 (with or without lto) but that is
part of another bug.
