failed to track some other panic msgs

[LinkShen]

Hi, recently I found that some specific panic type will be ignored. As the code shown below:

func trackPanic(r io.Reader, w io.Writer, dur time.Duration, result chan<- string) {
	...
	panicHeaders := [][]byte{
		[]byte("panic:"),
		[]byte("fatal error: fault"),
	}
	...
}

panicwrap only deal with these two kinds panic msgs. But I met:
"fatal error: concurrent map iteration and map write"
these kinds of panic will be ignored.

Another one: fatal error: sync: unlock of unlocked mutex.

Complete list of fatal error: for Go 1.19:

$ rg 'fatal[(]"' | sed 's/.*fatal("\(.*\)")/\1/' | sort -u
all goroutines are asleep - deadlock!
AllThreadsSyscall6 results differ between threads; runtime corrupted
concurrent map iteration and map write
concurrent map read and map write
concurrent map writes
go of nil func value
no goroutines (main called runtime.Goexit) - deadlock!
sync: RUnlock of unlocked RWMutex
sync: unlock of unlocked mutex
sync: Unlock of unlocked RWMutex

Well, actually it's not a complete list. There are a several hundreds throw("…") calls which also output as a fatal error:, e.g.:

$ ulimit -H -v 100000; ./app
fatal error: failed to reserve page summary memory
