dlve version: 1.6.0 and 1.6.1, i have tried these 2 version, but neither of them is useful
my simple file.go:
package main
import "fmt"
func main() {
a, b := 1, 3
c := a + b
fmt.Print(c)
}
my breakpoint line is c := a + b, but it didn't stop at that line, it just run to end and print 4
the simple program run log: panic: runtime error: index out of range [7542] with length 7542

if you need more information, please let me known
Version 1.6 of delve is old for go 1.22, you should first update delve to at least 1.22.0.
If updating doesn't work please post the output with --log --log-output=gdbwire.

oh, i copied the env of go 1.22 in the previouse comment, the env of go 1.6 is below:

Go very rarely breaks backwards compatibility, I think it would be worth revisiting your assumption that you have to use go 1.16.
You can use a more recent version of delve with the version check disabled, we don't test it but it probably works anyway. Or you can use an operating system that breaks backwards compatibility less. Or you can track down the patches to the debugserver backend (they are the ones that touch pkg/proc/gdbserial and make your own version of delve).

Thank you! I will try it.
