woboq codebrowser_generator segfaultsin llvm::sys::fs::detail::directory_iterator_construct(llvm::sys::fs::detail::DirIterState&, llvm::StringRef, bool) about codebrowser

I suspect the problem is that clang crashes while parsing the compilation database.
Can you try running valgrind, this will probably show some more details about what pointer was invalid.

Can you also run clang-tidy with this compilation database, if it crashes too that would confirm my assumption:

clang-tidy -p /home/tbr/src/icecast /home/tbr/src/icecast/conftest

Can you paste what is the compilation database for the file conftest ?
I have noticed that sometimes, empty file in the compilation database can cause problem.

You can use this line to remove the empty files and see if it fixes the problem

sed -i '/"file": ""/d' compile_commands.json

This might be caused by a bug in fake_compiler.sh that fails to parse the entry.

@dm8tbr Any news?

This had dropped off my radar, sorry.
I now updated both icecast and woboq sources to latest master, rebuilt both properly.

It still segfaults right after starting. After I ran @ogoffart's sed one-liner output changed mildly, but it still crashes.
