Global pointers initialized with
new[]did not get aBUFFER_SIZEvalue becausevalueFlowDynamicBufferSize()only handled allocations found inside function scopes.This change propagates the initial buffer size into
main(). The existing value-flow analysisinvalidate it after assignments or calls that may modify the global pointer.
Added regression tests for the reported out-of-bounds false negative, reassignment of the
global pointer, and an unknown function call that may modify it.
