    Hi,

    Preview.9-1.3.0 : Build fail
    Preview.8 : throws other errors (fixed on preview 9)
    Preview.7 : works fine.

    Code (CSharp):
    1. BuildFailedException: Burst compiler (1.3.0-preview.9) failed running
    2.  
    3. stdout:
    4. An unexpected exception occurred:
    5. stderr:
    6. Burst.Compiler.IL.CompilerException: Unable to find sleef function `Sleef_cinz_ldexpd1purec, Sleef_cinz_ldexpd1`
    7.    � Burst.Bcl.BclApp.CompileAndLink(List`1 libraryCompilationRequests)
    8.    � Burst.Bcl.Program.Main(String[] args)
    9.

    Hey there - I can take a look at this.

    Have you got a repro project I can look at?

    Also - can you confirm whether you've got deterministic floating point on?

    Assuming your issue is with determinism (I think it is) I've worked out a fix for that locally. Should be in the next preview.

    Yes. It fixed the error.
    Removing Standard/Deterministic. Only
    [BurstCompile(CompileSynchronously = true)]
    Thanks
