stackcollapse-hpl fails with "Exception: Unexpected marker: 21 at offset 14"

I get the following error when trying to parse a hpl file generated by honest-profiler (version d505d540ad09516ede804e7d1aa34a889f266780):

stackcollapse-hpl slow2 > output-folded.txt

Using https://github.com/RichardWarburton/honest-profiler/blob/master/src/main/java/com/insightfullogic/honest_profiler/ports/console/FlameGraphDumperApplication.java on the same file seems to work.

Hi Tomasz,

Thanks for the report. It has been a while since I last used honest-profiler (mainly using perf & flight recorder now). Work is piling up, but I will try to find some time next week to investigate whether it's a bug or if they evolved hpl format.

I just quickly troubleshooted the issue. This is due to e9b13fcea517af8b1a93be3e196591d1b466a723 which introduced a new type of log events. I will add support for this new log event soon.

I just pushed a fix into the master. Could you test it ?
