The tool fails on output produced by GHC 8.6.4

[mrkkrp]

It appears that if I run it with profiling output produced by GHC 8.6.4 it fails like so:

ghc-prof-aeson-flamegraph --profile-file valholl-new.prof --output-file valholl-new.txt
Error in $: Failed reading: satisfy

Maybe the format has changed a little bit and the tool should be updated?

You'll have to provide a bit more information. Just the very basic test seems to still work.

[nix-shell:/tmp]$ ghc -O2 -fprof-auto -prof -rtsopts -fforce-recomp M.hs && ./M +RTS -pj -RTS && ghc-prof-aeson-flamegraph --profile-file M.prof --output-file /dev/null; echo Exited with $?
[1 of 1] Compiling Main             ( M.hs, M.o )

[nix-shell:/tmp]$ cat M.hs
module Main (main) where

f :: Int -> Int
f = (* 5)

g :: Int -> Int
g = flip div 5

main :: IO ()
main = print . g $ f 20

[nix-shell:/tmp]$ ghc --version

I received a profile file that exhibits the issue privately a while ago. I'm a bit short on time so I don't know when I can look.

It’s OK, I made progress without flame graphs.
