SIGSEGV running Rust tests under kcov

Does the workaround @mthebridge uses (```--include-pattern=```) help for you as well?

SIGSEGV running Rust tests under kcov

Thanks for the insight into rust! Still, I don't think the missing source code as such is really the problem - that's quite common for C/C++ as well, and present...

SIGSEGV running Rust tests under kcov

@Dushistov try running kcov with `--verify`, it seems to be needed pretty much always with rust binaries.

kcov generates inconsistent output when there are files with duplicate names

Is this only for the summaries, or are the actual file contents wrong as well? kcov should handle this case, I had issues with non-unique filenames early on, although that...

kcov generates inconsistent output when there are files with duplicate names

Sorry, didn't realise this was on OSX. I'll try to reproduce it there (it was OK on Linux at least). It will probably be after the weekend though. Thanks for...

kcov generates inconsistent output when there are files with duplicate names

Are these subsequent runs on the same output directory, or is the output directory re-created each time? I.e, do you do ``` kcov /tmp/kcov kcov /tmp/kcov ``` or ``` kcov...

kcov generates inconsistent output when there are files with duplicate names

OK, thanks for the test. Then it's not the accumulation that got it wrong at least. I don't think the source layout should really matter, but I might be wrong....

kcov generates inconsistent output when there are files with duplicate names

One thing you could try is to run with ``` kcov --debug=1 ``` You should then see a lot of lines with file:line -> address mappings such as: ``` REPORT...

kcov generates inconsistent output when there are files with duplicate names

I think this is probably a separate issue, at least technically, since it's using the bash "engine" and the merge-mode. So probably a new issue would be good to have...

--verify fails for many addresses in a solib sometimes.

OK, this is an interesting variant of the "usual" problem of having to use --verify to workaround broken DWARF information. I agree it sounds like an issue with the BFD...
