Description
Version and Platform (required):
- Binary Ninja Version: 4.1.5261-dev Personal (859dedd4)
Bug Description:
HLIL will sometimes replace a writable data variable that contains a string with the value of the string.
Steps To Reproduce:
I believe this is enough:
Expected Behavior:
HLIL displays the assignment as data_1800b6088[0] = 0 or something.
HLIL displays the read (rcx_1 = ...) as rcx_1 = *data_1800b6088 or something.

Research direction
Reproduce the HLIL behavior using the supplied description and screenshots, focusing on writable data variables that contain strings. Compare the displayed assignment and read with the expected indirect data accesses. Done means HLIL no longer substitutes the string constant and instead shows the writable data variable or dereference as described.
