ICE: -flto and -g

[Adrian von Bidder <avbidder at fortytwo dot ch>]

Heyho!

I strongly suspect that mixing -flto and -g might not be a well supported 
option right now ...

Still I also suspect an ICE is not supposed to happen.  (I was trying to 
recompile Debian's KDE packages with -flto; the packaging by default uses -g -
O2)

gcc Debian package 4.5.0-2 on amd64 (x86-64)

+++
$ gcc-4.5 --version

Omitting either -flto or -g allows compiling successfully.

kfinddialog.ii at http://fortytwo.ch/~avbidder/kfinddialog.ii.gz since it's 
170k even compressed.  Sorry, I don't know enough C++ to even begin to reduce 
it; also, seeing as the Debian package seems to be built from a prerelease I'm 
not sure if this report is interesting.

cheers
