Also running into the same issue. Anyone know of a workaround?

[Azercoco]

I am also encountering the issue, did anyone found a solution ?

[jarbus]

Experiencing this as well, fixed by downgrading to version 2.3.0 for me

I also have this issue, but downgrading to 2.3.0 didn't fix it

Could someone who is experiencing this issue please upload the .pb.gz that has the problem? it should be in the CWD of wherever you are running pprof.

And cherry-on-top would be to provide a reproducible MRE that would let us demonstrate this ourselves!

This reproduces the issue for me on v3.1.0:

using PProf
@pprof map(sin, rand(1000))

Here's the generated profile.pb.gz

Affected by the same issue; I stepped through the code and produced #97 which appears to fix this. Please try and lmk if this works for you!
