Description

### What version of pprof are you using?
pprof latest, go tip

### What operating system and processor architecture are you using?

Ubuntu 22.04.2, amd64

### What did you do?

Tried to open a cpu pprof profile captured on my mac (darwin/arm64) on my linux/amd64 machine, then on the web ui navigate to: `http://localhost:3000/ui/disasm`

`pprof -http=:3000 profile.pprof` or `go tool pprof -http=:3000 profile.pprof`

### What did you expect to see?

With `go tool pprof` on Go 1.17 I see:

### What did you see instead?

Starting with go 1.18 the disasm page crashes:

Same for google/pprof latest

On console it says: `no matches found for regexp:`
