This seems convoluted. Can you instead run `pprof` command as a child process redirecting its output to a pipe that your program reads from?

Maybe that call is from https://github.com/google/pprof/blob/cf6d271c80826ef4d30d55512b5a77b115bd4b9c/internal/driver/cli.go#L98 where it sniffs the first argument to decide whether it's a binary or a profile?

If so, perhaps it might make sense to have a separate method to call like `o.Obj.Sniff` that would cheaply return a boolean whether the file looks like a supported binary...

My other guess would be that it could be from https://github.com/google/pprof/blob/cf6d271c80826ef4d30d55512b5a77b115bd4b9c/internal/driver/fetch.go#L437.

Could be. The profiles generated by gperftools should be in text format, can you take a look at what the mapping record section looks like in the input file?

What do the mappings look like in `pprof -raw `?

@Timmmm Which tool did you use to collect this profile? Is it from gperftools?

We don't plan to work on the feature any time soon, volunteers are welcome :)

Agree, this is useful.
