LLVM assertion with 16 codegen units and ThinLTO #45131
Comments

Thanks for the report! I'll try to investigate soon |
Same error comes out of the crate
|
I've opened up an upstream bug for this as well as a fix, and I'll backport this to our branch once it lands. |

This commit updates LLVM with a patch that's landed upstream to fix an assertion that was tripping when ThinLTO was activated. Unfortunately I wasn't able to get a reduced test case, but I've tested manually on the affected crates and the assertion is indeed fixed. Closes rust-lang#45131

The assertion error appears when compiling syn, but I could not reproduce with the syn crate by itself.
