[Bug c++/13389] sizeof in template:unimplemented: call_expr cannot be mangled due to a defect in the C++ ABI

Confirmed, somehow: this presently gives these error messages: 
 
g/x> /home/bangerth/bin/gcc-3.3.3-pre/bin/c++ -c x.cc 
x.cc:13: sorry, unimplemented: call_expr cannot be mangled due to a defect in  
   the C++ ABI 
 
And the same with mainline, even with -fabi-version=0. I don't know  
whether this still qualifies as a bug proper, but since it's not 
implemented we should keep it open.

I think we should just wait for the Itanium ABI commitee to update its ABI. See 
also this thread: http://gcc.gnu.org/ml/gcc/2003-06/msg01948.html

especially:
http://gcc.gnu.org/ml/gcc/2003-06/msg02018.html
http://gcc.gnu.org/ml/gcc/2003-06/msg02025.html

Mark, are there any news on this issue?

Not an enhancemente: it's an ICE on a valid piece of C++ code.
