its' a gold effect!
with 
ld -v
GNU ld (GNU Binutils) 2.21
things are fine
(gdb) run
Starting program: /afs/cern.ch/user/i/innocent/public/ctest/lto/t_hlto 
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7dfc78d in go(int, int const*) () from ./libfoo_hlto.so
Missing separate debuginfos, use: debuginfo-install
glibc-2.12-1.7.el6_0.4.x86_64
(gdb) where
#0  0x00007ffff7dfc78d in go(int, int const*) () from ./libfoo_hlto.so
#1  0x000000000040050d in main ()

I will stick to " bfd ld" for the time being. 
not sure on which side should be 
gold + gcc-lto-plugin 
debug.
gold is written in c++ which may mean that  bootstrap in the installation is
needed

thanks for the fast feed back,

vincenzo
