This looks like an argument slot getting clobbered. No obvious indication of what went wrong. The fact that the interface got clobbered twice is interesting. I suspect some sort of general heap corruption. Is there any way you can give us a means to reproduce this ourselves? It is going to be hard to track down otherwise. You might audit your use of the |

@randall77 cannot reproduce if i cherry pick partial code i have a package "planx"，and testcase in planx_test.go file package planx_test
import (
"testing"
"github.com/stretchr/testify/assert"
"github.com/stretchr/testify/require"
...
)
func TestPlanVisitor(t *testing.T) {
...
}now i create a new package "plan2", and copy planx_test.go to plan2/plan2_test.go, then change code line "package planx_test" to "package plan2_test". package plan2_test
import (
"testing"

}run command: go1.22.0 test -timeout 30s -run ^TestPlanVisitor$ github.com/timmy21/test/plan2 -v -count 1 -race test passed!!! what happen? |

I don't know. Without something I can run, it will be hard for me to figure it out. |

Ok, I can reproduce. Seems to be ok on darwin/arm64, but not on darwin/amd64. |
|
Ok, this seems sort of a strange situation. The compiler compiles the function I don't understand yet how the code compiles differently in the two cases. That seems like the underlying problem to fix. Although, we could paper over the problem by coming up with a more unique naming scheme for generated jump tables. |

Workaround in case you care: build with |

Ok, I may continue to use go1.21 until the issues are fixed by the way, test passed if remove -race. this is why? |

Strangely, bisect points to https://go-review.googlesource.com/c/go/+/545357 as the first failing CL. |
|
The difference in compilation is subtle. CL 545357 is implicated because it is the one that makes the different but equivalent The reason this happens differently when compiling So I think the underlying bug here is that we're using exact pointer equality during stack allocation. We should be using something more forgiving of different-pointer-but-same-type types. It does make me nervous that we're so dependent on having byte-by-byte identical compilation on two different invocations of the compiler. And that the linker didn't catch the discrepancy. |

The jump table symbol is accessed only from the function symbol (in the same package), so it can be static. Also, if the function is DUPOK and it is, somehow, compiled differently in two different packages, the linker must choose the jump table symbol associated to the function symbol it chose. Currently the jump table symbol is DUPOK, so that is not guaranteed. Making it static will guarantee that, as each copy of the function symbol refers to its own jump table symbol. For #65783.

Currently we use pointer equality on types when deciding whether we can reuse a stack slot. That's too strict, as we don't guarantee pointer equality for the same type. In particular, it can vary based on whether PtrTo has been called in the frontend or not. Instead, use the type's LinkString, which is guaranteed to both be unique for a type, and to not vary given two different type structures describing the same type.
