GL renderer crashes in a map with mirror+portal+skybox
Posted: Sat Dec 15, 2018 8:24 pm
Stack trace is against Git revision c92e6b03ac461ac16c13412ae414332145e60081.
The "725f3332()" is apparently virtual delete in HWPortal.
Steps to reproduce:
1. Make sure you have vid_rendermode=4
2. Use the map attached (IWAD=doom2.wad). The reflective floors are 1.0 reflective on purpose — makes it easier to spot the issue.
3. Position yourself at roughly (-3289, 488, 32)
4. Make sure you see this: https://i.imgur.com/2K8e5sI.png (this is on it's own a problem, but not related and not visible in production map so w/e)
5. Move around for a bit, turn camera around. It will crash at some point
You can try the attached demo. For me it crashes reliably (and differently every time!)
