Possibly related error.

@dfaure-kdab An idea? :)

[ThijsWithaar]

Same problem over here, using debian buster.
Hotspot itself can't find debug symbols, not sure if that's related.

[dfaure-kdab]

@nwrogers, as far as I can see this is your code? ;)

If this needs @milianw then it'll have to wait until beginning of December, unfortunately.

[milianw]

Can you guys try again with the latest git please?

[ThijsWithaar]

Yes, just did. The flamegraphs work fine. Thanks!

tst_perfparser still fails for me using latest master (72e68b9) on Ubuntu 19.10 with the following output:

[milianw]

yes, that test really needs some love - it's an integration test that is highly platform dependent and thus probably not a really good way to test what it does... for now, please ignore it ;-) or fix it!

Just FYI: Test is working with current master Using QtTest library 5.15.2, Qt 5.15.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 9.3.0), ubuntu 20.04
