In the QContainerImplHelper::mid function (qtbase/src/corelib/tools/qarraydata.h:189), there is an integer overflow issue when processing INT_MIN as the position parameter.Specific Issue:When position = INT_MIN and length = INT_MAX, the calculation of length + position causes integer overflow:

• On 32-bit systems: INT_MIN = -2147483648, INT_MAX = 2147483647

• length + position = 2147483647 + (-2147483648) = -1

This leads to unexpected behavior and may return incorrect results.
