>Description:
In stl_tree.h,
function _Rb_tree_rebalance(_Rb_tree_node_base* __x, _Rb_tree_node_base*& __root)
Line: 312
if (__x->_M_parent == __x->_M_parent->_M_parent->_M_left)
In my test code, __x->_M_parent->_M_parent == 0x0, so during the attempt above to get the left node of 0x0, the software crashes. I am trying to figure out where the node should have been initialized, but meanwhile, placing this bug report. I am writing an allocator.
Thanks,
Marc
>How-To-Repeat:
Works with generic STL calls when no allocator specified but not with my allocator. I believe that my allocator matches the standard allocator interface. I am not sure what, if anything might else be needed.
Still studying this issue. Early report
