Fixes CLIENT-177. The issue was that: Delegation to an invalid
AlternateUnicodeFontobject during text extent calculation causes a fatal write access violation inStore_GDI_Char.UnicodeCharArrayis allocated and the index is valid before retrieving character data.BufferListis not empty and the last element is not NULL before accessing the current font buffer.current_buffer) immediately afterUpdate_Current_Buffer()to prevent potential race conditions.UnicodeCharArray.This fix was generated by Seer in Sentry, triggered automatically. 👁️ Run ID: 8001435
