@davleopo I've confirmed the dedicated server crashes as well, here's a log: [cmd.log](https://github.com/oracle/graal/files/9295197/cmd.log) But I've made a interesting discovery. The Minecraft dedicated server, by default, launches a little window showing...

Excellent, thanks! Disabling PartialEscapeAnalysis has a ~6% hit in a Minecraft chunkgen benchmark, but its still much better than disabling PriorityInlining: [benchmark-2022-08-12_19-15-12.json.txt](https://github.com/oracle/graal/files/9330521/benchmark-2022-08-12_19-15-12.json.txt) ...but on the other hand, `Dgraal.PartialEscapeAnalysis=false` seems to...

Are there any narrower flags I can try? I'm looking through the output of `+JVMCIPrintProperties`, but I'm not sure what falls under the umbrella of `VectorizeSIMD`

An interesting twist: this error seemingly requires `Dgraal.UsePriorityInlining` to be set to false. I can't get it to occur when it is set to true. This is impossible to test...

I have narrowed down the bug and realized I am off track here, so I am going to close this issue and start a new one with more concise information.
