Source Build Editor Locks up when using Output Log Viewer

I am running a source build of the Editor version 4.7.2. No source modifications, Development Editor Win64 Target. I have uninstalled (removed the code from the tree and project) my plugin that I’m developing just to verify that it was not causing the issue. To replace the issue:

  1. Execute the Editor by opening a project file, or by launching via Visual Studio Express. Can be replicated in either mode of execution.
  2. Wait for startup to complete
  3. Open the Output Log Viewer
    At any point in time after this the editor will Stop Responding to windows input and messages. It’s not always immedate, but it will not happen unless the Output Log viewer is open. I frequently use the mouse wheel to scan through the viewer contents.

Once it locked up in debug mode i halted execution. Every time it was halted on Line 197 of TextStoreACP.cpp, what looks to be a mutex or semaphore lock from the MAIN THREAD. Attached is the log file from the execution failure. I can find nothing in this log file to indicate what may be going wrong. link text

This sounds like this issue: [4.5] The Output Log degrades performance - Debugging, Optimization, & Profiling - Epic Developer Community Forums

Merging in 23cb8cbc5b90b684f65edd2c0a21a731d219fd56 should fix it for you.

I have merged in the suggested fix. I’ll update this again if it recurs. Otherwise I assume this will fix it, and thank you for the assistance Jamie.
