System: Linux karma 2.2.16-22 #1 Tue Aug 22 16:49:06 EDT 2000 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../egcs/configure --prefix=/usr/local/egcs --enable-threads=posix
>Description:

G++ crashes on the source below when the -O switch is used.
The workaround i've been using is to compile the affected modules
without optimization.

>How-To-Repeat:

-----------------------------------------------------
struct TBtItem
{
   TBtItem();
};


struct TBtInnerNode
{
   TBtInnerNode();
   int     MaxIndex() const { return 10; }
};


TBtInnerNode::TBtInnerNode()
{
   new TBtItem[MaxIndex()+1];
}
-----------------------------------------------------


$ ./cc1plus -O x.cc
 int TBtInnerNode::MaxIndex() const TBtInnerNode::TBtInnerNode() TBtInnerNode::TBtInnerNode() TBtInnerNode::TBtInnerNode() TBtInnerNode::TBtInnerNode()
x.cc:10: Internal compiler error in copy_body_r, at cp/optimize.c:317
