Hi,

I caught a situation when just opening file with vim I got this within few seconds:

Exception KeyError: KeyError(140218199963392,) in module 'threading' from '/usr/lib/python2.7/threading.pyc' ignoredVim: Finished

Any ideas why?

Thanks.

Looks like clang bug but clang compiles code just fine.

Adding backtrace:

Ok, there's something going on here. You are not the first person to report the KeyError message. Issues #543 and #361 seem related, although those issues result in crashes.

I'm rewriting the YCM threading system for issue #358 which should resolve this as well. So #358 tracks this.

[READY] Some of the preprocessor flags take file arguments

Fixes ycm-core#534

Some of the pre-processor flags that we blacklist take file arguments, but were not registered as doing so.
