Tested in a fresh 32-bit prefix.
How to reproduce: 1. Launch wineconsole 2. Launch ITHVNR.exe 3a. Click "Process" 3b. Select wineconsole from the process list 3c. Click "Attach" 3d. Click "OK"
Expected result: text displayed by wineconsole is shown in ITHVNR when it's modified (ExtTextOutW hook, second dropdown)
Actual result: wineconsole segfaults shortly after attaching (no terminal output other than Segmentation fault)
These results can be reproduced with many 3rd-party programs too, I used wineconsole here for easier testing since it's shipped with Wine.

I can't reproduce the issue on 6226be3~1, wine-5.8 with 6226be3 reverted and wine-5.4 (last release before 6226be3). I can reproduce the bug on 6226be3, wine-5.5, wine-5.8 and 4358ddc75fbfabdc4a4f31b4e3cc9aa1e0811d4c (current master as of now).
