If you want a nice tarball with a ready-to-go repro case, I've put it here:

https://www.uplinklabs.net/files/lto-65828.tar.xz

Should just be able to run something like:

$ /usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/lto1 -quiet -dumpdir .libs/
-dumpbase libglib-2.0.so.0.4400.0.wpa -mtune=generic -march=x86-64
-mtune=generic -march=x86-64 -auxbase libglib_2_0_la-gallocator -O2 -O2
-version -fno-trapv -fPIC
-fltrans-output-list=libglib-2.0.so.0.4400.0.ltrans.out -fwpa
-fresolution=libglib-2.0.so.res @ccWGeoup.args

from inside the extracted directory and see the issue.

--- Comment #2 from Steven Noonan <steven at uplinklabs dot net> ---
I just noticed that libtool appears to be stripping some of the arguments in
LDFLAGS when invoking GCC:

/bin/sh ../libtool  --tag=CC   --mode=link gcc -flto -Wall -Wstrict-prototypes
-Werror=declaration-after-statement -Werror=missing-prototypes
-Werror=implicit-function-declaration -Werror=pointer-arith -Werror=init-self
-Werror=format=2 -Werror=missing-include-dirs -fvisibility=hidden -O2
-fsanitize=undefined -Wl,-Bsymbolic-functions  -version-info 4400:0:4400
-export-dynamic  -O2 -fsanitize=undefined -o libglib-2.0.la -rpath
/usr/local/lib [[.lo files]] libcharset/libcharset.la pcre/libpcre.la 
-lpthread

libtool: link: gcc -flto -shared  -fPIC -DPIC  [[.o files]] 
-Wl,--whole-archive libcharset/.libs/libcharset.a pcre/.libs/libpcre.a
-Wl,--no-whole-archive  -lpthread  -flto -O2 -Wl,-Bsymbolic-functions -O2  
-Wl,-soname -Wl,libglib-2.0.so.0 -o .libs/libglib-2.0.so.0.4400.0

In particular it dropped the -fsanitize=undefined flag.

If I invoke the libtool-generated GCC command line with '-fsanitize=undefined'
added then there's no ICE.

$ gcc -flto -shared  -fPIC -DPIC  [[.o files]]  -Wl,--whole-archive
libcharset/.libs/libcharset.a pcre/.libs/libpcre.a -Wl,--no-whole-archive 
-lpthread  -flto -O2 -Wl,-Bsymbolic-functions -O2   -Wl,-soname
-Wl,libglib-2.0.so.0 -o .libs/libglib-2.0.so.0.4400.0 -fsanitize=undefined
$ ls -cahl .libs/libglib-2.0.so.0.4400.0
-rwxr-xr-x 1 snoonan snoonan 4.3M Apr 21 03:31 .libs/libglib-2.0.so.0.4400.0

Hmm.

I remember seeing patches for this kind of issue (for GCC 5 at least).  Maybe
somebody remembers.

ICE in streamer_get_builtin_tree doesn't ring a bell for me, sorry.

I just run it with gcc-5.2.0 and I got the following error:

That is expected. Using lto files from older compilers is not supported.

--- Comment #3 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
The problem initially reported in this bug is now fixed in the git branch
aoliva/pr64164.  I'm not sure how to go about duplicating the one in comment 1,
but, having fixed a number of additional split_complex issues since the patch
that caused the problems was put in, I hope it's fixed too.  Gary, would you
please detail the toplevel configure and build command lines to trigger it, or
perhaps give the branch a try and confirm that it fixes the problem?  Thanks,
