Description

Version and Platform (required):

  • Binary Ninja Version: 4.0.4836-dev, df4290fd
  • OS: macos
  • OS Version: 14.3
  • CPU Architecture: arm64

Bug Description:
It seems that BN chooses to display bool values as false or true, but it does so inconsistently. In the example below, initialized is defined as a bool. As evident in the example, BN uses true or false when assigning a value to it. However, when checking its value in if statements, it does not maintain this consistency.

Research direction

The report names no source file, test, or entry point. Start by reproducing the inconsistent bool display in Binary Ninja 4.0.4836-dev on macOS 14.3 arm64, comparing the assignment and conditional views shown in the screenshot. Trace the relevant display path and verify that both contexts render bool values consistently.
