I can reproduce this error on linux with Julia 1.5.0. julia> Iterators.flatten((tuple(nlb),Iterators.flatten( (tuple(i) for i in [unicode])))) |> collect

re"(?<!\(\:)"
re"[#$(isvalid)]"The example is working as expected in 1.4.1. |

I have prepared rr traces. Interestingly, on ubuntu linux I get segmentation fault errors, rather than the errors I posted above. https://s3.amazonaws.com/julialang-dumps/reports/2020-08-04T13-22-00-mosheduminer.tar.zst rr trace for the second code block: https://s3.amazonaws.com/julialang-dumps/reports/2020-08-04T13-24-08-mosheduminer.tar.zst |

Hmm, there seems to be something wrong with those traces - they appear to be corrupted. Did something go wrong during recording? |
Not that I am aware of... I have uploaded another trace here, for the first code block. Is this one okay? |
|
Your traces keep ending up being exactly 76 bytes. Are you perhaps on an unsupported platform - maybe the code that is supposed to error out there broke? |
|
I did the traces on an ubuntu distro (zorin 15, based on 18.04). I don't know why they are corrupted... 🤷 |
|
@SimonDanisch complained that some of the fatal errors weren't sufficiently noisy (JuliaLang/BugReporting.jl#24), perhaps you had the same issue? |
|
I don't know... And as I mentioned, I got segfaults on linux, instead of the LLVM errors I got on windows. EDIT: if I recall correctly, julia did not ask me to report the bug after the segfaults on linux. |

Fixed by #39801 (confirmed by backporting that commit, since CombinedParsers.jl doesn't currently work on v1.6) |
I was playing with the
CombinedParsers.jllibrary, when I got an LLVM error. Upon further attempts with related code, I got other LLVM errors. The following is the code for the first error:Running the last line (this was in the REPL) caused the following output:
The code for the second error is as follows:
Running the last line (in the REPL) caused the following output:
I am sure that the implementation of CombinedParsers is relevant here, but I have no idea how it works.
