Folder structure:

package main
import "core:slice"
import "my_search_2_package"
main :: proc() {
arr := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
// #1 works
for v in arr {
_, _ = slice.binary_search(arr, v)
}
// #2 works
for v in arr {
_, _ = my_search_1(arr, v)
}
// #3 works
for v in arr {
_, _ = my_search_2_package.my_search_2(arr, v)
}
// #4 works
for v in arr {
_, _ = my_search_3(arr, v)
}
// #5 works, my_search_1 is inside current file
wrapped(arr, my_search_1)
// #6 works, my_search_3 is inside different file, but same package
wrapped(arr, my_search_3)
// #7 doesn't work, imported from different core package
wrapped(arr, slice.binary_search)
// #8 doesn't work, imported from different local package
wrapped(arr, my_search_2_package.my_search_2)
}
wrapped :: proc(arr: []$T, search_proc: (proc(arr: []T, value: T) -> (int, bool))) {
for v in arr {
_, _ = search_proc(arr, v)
}
}
my_search_1 :: proc(arr: []$T, value: T) -> (int, bool) {
return 0, false
}
bodies of my_search_2_package.my_search_2 and my_search_3 are same as my_search_1
Now programs crashes, but if you comment case 7 wrapped(arr, slice.binary_search) and case 8 wrapped(arr, my_search_2_package.my_search_2) program will work fine
Crash only happens if we import procedure from another package and pass it to wrapped proc. If we pass procedure declared in the current file (not imported from another package) it works fine
Failure Logs
Program's output:
D:\a\Odin\Odin\src\llvm_backend_general.cpp(1419): Assertion Failure: `addr.addr.value != nullptr`
This is a compiler error. Please report this.
