>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
