Description
Binary Ninja Version: 3.4.4090-dev Personal
Platform: Windows 11 Version 22H2
Stack view:
HLIL:
As you can see from screenshots, even if dwFlags, hStdInput, hStdError, hStdOutput, wShowWindow did used in the HLIL, stack view does not detect them (so they are grayed out and says "Not used in current IL" on hover).
I guess it only detect the first used element in the structure. Because in other examples I can see that it only detects first used element and then left the others undetected. Probably it assumes first element of the structure is equal to structure itself in regards of referencing.

Research direction
No source file, test, or entry point is named. Start by reproducing the reported structure usage in the Stack view and comparing it with the HLIL view, focusing on dwFlags, hStdInput, hStdError, hStdOutput, and wShowWindow. Done means every structure element used in HLIL is recognized by Stack view rather than shown as unused.
