Confirmed.

I will have a looksee.
Comment 4 Richard Biener 2010-04-22 15:22:10 UTC 
It's TYPE_ARG_TYPES of a FUNCTION_TYPE when writing the FUNCTION_DECL of
void_cast_register which isn't instantiated.

Reducing.
Comment 5 Richard Biener 2010-04-22 15:40:19 UTC 
Reduced testcase:

template <class T> void void_cast_register(T *) __attribute__ ((used));
template <class T> void void_cast_register(T *) { }

Comment 9 Matt Turner 2010-08-22 22:02:39 UTC 
Can this code be backported to the 4.5 branch?
Comment 10 Andrea Bigagli 2010-09-02 22:38:14 UTC 
What is the changeset that fixed this on trunk? I'd really need to try to patch my 4.5.1 if possible bcs this bug is a showstopper for me

LTO is an experimental feature for 4.5.x.  That is it has been tested but there could be some bugs in it.  It is designed to be able to test it and see the improvements that are coming.
