Works for me

So I guess the problem is fixed at 4.6 branch - there was a lot of improvments
for plugin symtabs there.

[Bug lto/41782] New: lto/gold: -flto -user-linker-plugin dies with internal error in gold

[edwintorok at gmail dot com]

When trying to compile and link the attached not.i with lto the linker dies
with this error:
/usr/bin/ld: internal error in set_linkonce_size, at ../../gold/layout.h:250

This only occurs if I use -use-linker-plugin, so I think this may be a bug in
gcc's gold plugin, so I'm filing this as a gcc  bug (but it may also be a bug
in gold triggered by lto).

To reproduce:
$ /home/edwin/inst/bin/g++ -flto -c not.i -o not.o
$ /home/edwin/inst/bin/g++  -shared -flto -use-linker-plugin    not.o
/usr/bin/ld: internal error in set_linkonce_size, at ../../gold/layout.h:250
collect2: ld returned 1 exit status

$ /home/edwin/inst/bin/g++ -v
Using built-in specs.
