@sfc-gh-sgiesecke it would be nice if llvm-addr2line would transparently support the gsym format instead. It doesn't look right that tools like pprof need to dispatch on different file formats supported...

This seems similar to how *.dwp files are supported. There could be a default of looking up next to the binary or something. In any case, this is something that...

@odeke-em Is it possible to add a test that fails before the the change and passes after?

> The trouble might be that folded stacks format only accepts one output number per stack, but pprof can have multiple numbers per stack. So we'd probably have to choose...

The cockroachdb folks integrate pprof into their service I think - https://github.com/cockroachdb/cockroach/blob/2eebbddbb133eea7102a47fbe7f5d13ec6f8f670/pkg/server/debug/pprofui/server.go#L169. @p1gd0g Is this what you need or you mean something else by "reuse"?

Could you run `dpkg -S /usr/bin/pprof` command and paste the output here? I have a suspicion that you are using the [previous incarnation of pprof from gperftools](https://github.com/gperftools/gperftools/blob/master/src/pprof). If so, you...

Yes I think the theory was wrong. Looks like pprof from this repo does think that the first profile has 2 metrics only: ``` $ pprof -tags -sample_index 5 envoy.hprof.0001.heap...

@jmarantz Could you confirm that all profiles here were from the same program run? That is, I want to confirm that the 0001 file was not generated in a separate...

This should be a separate tool that pprof invokes, we don't really want to integrate the code for parsing the java heap dumps too deeply in the code.

@rjogrady - please feel free to send a PR.
