Bug#833802: clang-tidy-3.9: readability-identifier-naming segfaults

[paul cannon]

Package: clang-tidy-3.9
Version: 1:3.9~svn274438-1
Severity: normal
Tags: upstream, fixed-in-experimental, fixed-upstream

Running clang-tidy-3.9 with the "readability-identifier-naming" check
enabled fails with a segmentation fault at the slightest provocation:

    paul at turing:~$ cat breaks-clang-tidy.cpp 
    #include <iostream>

    int main()
    {
        return 0;
    }
    paul at turing:~$ clang-tidy-3.9 breaks-clang-tidy.cpp -checks='-*,readability-identifier-naming'
    Error while trying to load a compilation database:
    Could not auto-detect compilation database for file "breaks-clang-tidy.cpp"
    No compilation database found in /home/paul or any parent directory
    json-compilation-database: Error while opening JSON database: No such file or directory
    Running without flags.
    Segmentation fault
    paul at turing:~$

This matches the behavior complained of in the upstream bug at
https://llvm.org/bugs/show_bug.cgi?id=28481 , and the patch attached to
that bug does indeed fix the problem.

The problem is also fixed in version 1:3.9~svn275918-1~exp1 (in
experimental).
