I forgot to mension that, it stops with totaly safe (default) c{xx|ld}flags via package.env Let me know if you need that output/build.log too.
Does it build with earlier versions of GCC?
GCC-4.8.3 and binutils-9999 It builts just fine. Even with LTO -fomit-frame-pointers and other various CFLAGS. So...GCC-4.9.1 bug?
If you like to test another way please stop using -ffat-lto-objects and use git binutils with automatic loading of liblto_plugin.so. To have it loaded have a symlink from /usr/libexec/gcc/x86_64-pc-linux-gnu/4.9.1/liblto_plugin.so to /usr/x86_64-pc-linux-gnu/binutils-bin/lib/bfd-plugins/ set/present. Gcc:4.9 defaults to slim LTO, saving one compilation (-ffat-lto-object compiles once for normal/native assembler and once for GIMPLE bytecode) and above method allowed me to build cmake without froubles with gcc-4.9.2 svn version 215199.
I see. I thought it was incorrent to use -ffat-lto-object with lto symlink and binutils-9999 (steps that I have done already). So, should I remove it completeley and emerge system|world? Is this the correct way to enable/compile with LTO?
Also is -fuse-linker-plugin needed in CFLAGS when an lto symlink exists?

Shouldn't it be the gcc ebuild task to make that symlink?

Compiled ok with dev-util/cmake-3.1.0 and gcc-4.9.2
(In reply to Anton Kochkov from comment #11) > > Compiled ok with dev-util/cmake-3.1.0 and gcc-4.9.2 It would be good if you tell us what you're doing to enable lto so we can better support this in the future.

No special env file is needed. I am not using LTO, for the record. Do you want me to enable it and post the results after compiling cmake again?
