GCC 5.5 is buggy

[Yuri]

Easy to check.

My setups, installed from repo, was not contain lto* here:

# ls -al /opt/csw/libexec/gcc/i386-pc-solaris2.10/5.5.0/
total 162323
drwxr-xr-x 4 root bin         15 Mar  2 10:54 .

liblto_plugin.so.0.0.0
lrwxrwxrwx 1 root root        22 Mar  2 10:54 liblto_plugin.so.0 ->
liblto_plugin.so.0.0.0
-rwxr-xr-x 1 root root    293084 Mar  2 10:54 liblto_plugin.so.0.0.0
-rwxr-xr-x 1 root root    673020 Mar  2 10:54 lto-wrapper
-rwxr-xr-x 1 root root  16624004 Mar  2 10:54 lto1
drwxr-xr-x 2 root root         3 Mar  2 10:54 plugin

and, especially, this one:
/opt/csw/libexec/gcc/i386-pc-solaris2.10/5.5.0/plugin/gengtype

Now is ok, because of I've built all boxes GCC from source.

Sorry, can't give any sources wich dependent from LTO - all of them is
either dependent from a lot external dependensies, or commercial (not
open source).
