Hello everyone,
My application occasionally crash when processing string variables. I can
not provide you with the full example, but the code looks more or less like
this:
package main
import "fmt"
type Event struct {
tokenA string
tokenB string
tokenC string
tokenD string
}
func tokenLookup(tokens []string) {
for _, token := range tokens {
fmt.Println(len(token)) // this will return the length of the string
correctly
fmt.Println([]byte(token)) // this will panic
fmt.Println(token) // this will panic
}
}
func processEvent(event *Event) {
tokenLookup([]string{
event.tokenA,
event.tokenB,
event.tokenC,
event.tokenD,
})
}
I tested this and have the same problem when 1.6.2 and 1.7 versions.
Panic message look like this:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x45cc71]
goroutine 350 [running]:
panic(0x95c1a0, 0xc420016130)
/home/adwinsky/go/src/runtime/panic.go:500 +0x1a1
Anyone would like to help me with debugging or maybe have an idea what
could cause that?
Cheers
Adam
