Created attachment 7650
  --> http://llvm.org/bugs/attachment.cgi?id=7650
example Xcode project

I am using lib clang ( clang version 3.1 (trunk 144457) ) to build a code
editor on OSX.

When I type a single column ( ':' ) character inside the implementation of a
class in an objective-C (.m) file, clang_reparseTranslationUnit() sends a
signal and terminates the program.

I also noticed that clang_reparseTranslationUnit() is very slow ( too slow to
keep up with my typing to do lexical highlight, i.e. using clang_tokenize()
without clang_annotateTokens() ) when reprising a .h file, while it's much
quicker when reparising a .m file that includes that very same .h file.
