Steps to reproduce:
1. Open the “IN-120871” project
2. Wait a bit for the Burst libraries to compile
3. Observe the crash

Reproducible with versions: 1.7.4 (6000.0.70f1), 1.8.28 (6000.0.70f1, 6000.3.11f1, 6000.4.0b11, 6000.5.0a8)

Not reproducible on: no other environment tested

Note: if no crash occurs after Burst libraries are done compiling, try deleting the project's library folder
