I am unable to reproduce.

Are you on the branch? I have this: $ git checkout zig_assert_ir_analyze_container
$ git describe --long --all

that was it -- wrong branch -- can reproduce now fyi, it's tedious but you can isolate tests by filtering. This can be isolated further. |

@LemonBoy Thanks for helping me find where this error comes from! It is a bit strange to me that just moving the @mikdusan Thanks for the testing tip! I will try try it out |

@LemonBoy Hey you're right – just casting it fixes that assertion and tests passing again! diff --git a/src/czpeg.zig b/src/czpeg.zig

@LemonBoy I'll put together a PR for this if you're not doing it already? |

Yea, that's great! I could probably debug from that; and esp like "opaque has no fields" extra hint. (although, maybe "opaque type ..." could be clearer if the reader wasn't familiar where it's coming from?) I built this PR and can confirm that it also fixes the assertion for me. Is there any plan to make this work without the cast in the future? I'm sure there is subtle context here that I don't have, but to me "compile-time duck typing" means that if the compiler knows the thing has a method (which it must, somewhere, because I can test for and cast it), then we should be able to call that method without extra ceremony? Thanks for your help! yinz rock 🤘 |
I believe so. LemonBoy has a better idea than just this error fix and might give that a go if it's not too complex. |

While trying to factor some comptime arguments into a struct for cZPeg, I ran into this:
The code to reproduce is here: https://github.com/spadix0/cZPeg/tree/zig_assert_ir_analyze_container
that may not compile even without the assertion, but all tests pass before the branch, so something in that (small) diff probably triggered the problem(?)
