error trying to view prof file: user error (endOfInput)

[rintcius]

I got the following error when trying to view the attached prof file:

user error (endOfInput)

purs.prof.txt

Relevant stack.yaml: https://github.com/purescript/purescript/blob/master/stack.yaml

Thanks for reporting the issue. It looks like a bug in the GHC profiler where the module names and the cost center IDs can be concatenated. See the line 424 of your profiling report for example.

I'll see what we can do to work around this issue.

It could be fixed by this one: https://ghc.haskell.org/trac/ghc/ticket/8811 . Coincidentally, the ghc version is just upgraded in purescript too, so I'll retry with those updates & see if it's resolved now.

That looks like the same issue! I guess I can implement some workaround for GHC < 8.0 in this weekend.

I tried with ghc 8.0.2 but this gives a "ghc: panic". This bug is fixed in ghc HEAD though: https://ghc.haskell.org/trac/ghc/ticket/13503

Just uploaded v1.4.0.1 which has a workaround for this issue.

BTW just wondering how you're using this library. Are you using profiteur or viewprof, or using it directly in your app?

Great, thank you!

I am using both profiteur and viewprof.
