g++ segfaults on the example below if -Wall is used:

$ ./cc1plus -quiet -Wall x.cc
x.cc: In function `void t_test1(C*)':
x.cc:8: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
$

Here's where it's crashing:

Program received signal SIGSEGV, Segmentation fault.
0x0815480b in warn_for_collisions_1 (written=0x400f5cb0, writer=0x40008240,

It looks like this is more fallout from Richard's recent changes.

Environment:
System: Linux karma 2.6.7 #16 Tue Jun 22 21:52:28 EDT 2004 i686 i686 i386 GNU/Linux
Architecture: i686

	<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: /home/sss/gcc/gcc/configure --prefix=/usr/local/gcc --enable-threads=posix --enable-long-long --enable-languages=c,c++,f95

How-To-Repeat:

Compile with -Wall:

----------------------------------
struct C
{
  ~C() throw();
};

void t_test1 (C* mapping)
{
  delete [] mapping;
}
