test.c

We knew about that (and had some patches in this direction, 
for example D38319 and others), but I do not think we had
a realistic use case before. And it was probably not
documented in bugtracker.

I found this issue in binutils bugtracker today and
verified it is reproduced with use of LLD head.
(for reference: <a href="https://sourceware.org/bugzilla/show_bug.cgi?id=21066">https://sourceware.org/bugzilla/show_bug.cgi?id=21066</a>)

test.c is attached. When compiled and linked with LLD and --icf=all
it crashes:

./test 
caught expected exception
ERROR: caught unexpected exception
terminate called after throwing an instance of 'second_exception'
Aborted (core dumped)

without ICF output is:
./test 
caught expected exception
caught expected exception</pre>
