Description
Steps to repro:
- Open the provided database
- Go to the enum
API_namesin the types view - Add a new member with name
LoadLibraryAand value0x726774c - Notice the
API_resolverdoes not populate theLoadLibraryAname - Re-analyze the
load_wininetfunction, and see it does show up
After manual re-analysis
We are probably missing an analysis update not properly marking the function as needs update after we add the enum member

Research direction
Start with the provided database and reproduce the enum update in the types view, then compare the initial state with manual re-analysis of load_wininet. Trace how adding the API_names member affects API_resolver and function invalidation. Done means the LoadLibraryA name appears without manually re-analyzing the function.
