I got the 'below array bounds' warning in some code and could reduce it to the
following testcase (which results in the 'above array bounds' warning). The
warning occurs with optimization level -O2 and above.
gcc version 4.3.0 20070622 (experimental)
g++-4.3 -c -W -Wall -O2 asiaab.cpp --save-temps
asiaab.cpp: In function 'void f()':
asiaab.cpp:5: warning: array subscript is above array bounds
================
#include <vector>
void g()
{
std::vector<int> *A = new std::vector<int>[42];
delete[] A;
}
================
The warning does not occur with types e.g. 'int' or 'std::pair<int,int>'
instead of 'std::vector<int>'.
