| Summary | flightgear crashes on r600 (rs880) |
| Severity | normal |
| Classification | Unclassified |
| OS | Linux (All) |
| Reporter | marvin24@gmx.de |
| Hardware | x86-64 (AMD64) |
| Status | NEW |
| Version | git |
| Component | Drivers/Gallium/r600 |
| Product | Mesa |
flightgear 2.12 crashes on git mesa. Works with R600_LLVM=0. I initially
thought it is due to missing trig functions, but after applying a workaround
(from some other bug), it still crashes, so this must be something different.
