The check is there because |

Ok, build Julia again with: got this segfault: |
|
Honestly a bit surprised to see No shmem or add there |
|
The atomic add is coming from the derivative. It appears that A[i] wasn’t proven an entirely thread local location so it falls back to an atomic add edit: or never mind that is coming from some other calling context code |
Are you using Julia 1.9? That version is not supported. You need to use an LLVM assertions build based on Julia's |
|
I was using Julia v 1.7.1 for the initial segfault, but built the lastest version of Julia for the llvm assertions segfault above. Here is the error on |
|
This looks quite similar to the 1.7.1 segfault to me. Maybe I built julia with LLVM ASSERTIONS wrong? I created a Make.user with: and then ran |
|
You can check with LLVM.jl if your LLVM build has assertions. |

Pasting here (so I remember how to check whether I built with LLVM assertions in the future): |

Can you dump the bitcode before it calls |

Looks fixed on LLVM ToT. I'll try bisecting. |
@vchuravy This (and the reduced bitcode) should help you figure out what's wrong. Backporting the commit is the easy fix, but Enzyme.jl is probably somehow botching the debug info. |

Thanks Tim for narrowing it down! Yeah Enzyme is a bit laissez-faire about
debuginfo.

[DWARF][FIX] Try not to crash for nvptx with missing debug information
This prevents crashes in the OpenMP offload pipeline as not everything
is properly annotated with debug information, e.g., the runtimes we link
in. While we might want to have them annotated, it seems to be generally
useful to gracefully handle missing debug info rather than crashing.
TODO: A test is missing and can hopefully be distilled prior to landing.
This fixes #51079.

@maleadt @vchuravy this appears not to be a bug in Enzyme.jl, since even the original module itself (i.e. without Enzyme codegen) triggers the problem (and namely there is no debug info on the function itself, whereas the instructions inside have it). mod = ; ModuleID = 'text'

Okay, turns out its in an Enzyme.jl wrapper LLVM function. |

I have been messing around with the new CUDA tests in Enzyme and realized that they all fail on and after
CUDA#36488fb336b3f518857e933d2c44e94c3bafddc6: JuliaGPU/CUDA.jl@6c771c6 (Full error message below).@vchuravy seems to think Enzyme might be outputting iffy debug info. Related: https://github.com/JuliaGPU/CUDA.jl/blob/04b98b1ebee0911be7902659f20e28446d8de080/src/compiler/gpucompiler.jl#L40
Note that the code runs fine when running julia with
-g0@maleadt
