Description Jonah Graham CLA 2021-11-12 19:39:58 EST 
Calls to ScriptItemize allocates huge buffers to accommodate for worst case ScriptItemize results all the time.

The design of ScriptItemize is that a "typical" sized buffer is used, and if ScriptItemize returns E_OUTOFMEMORY then the buffer size is increased.

At the moment the size of the buffer is the length of the string (+2) x sizeof SCRIPT_ITEM (which is 8 bytes).
