Description
The clang code model fails to parse any files which include a precompiled header is included using the -include of the compiler.
I can reproduce the problem in both 4.9.0 and 4.10.0-beta2. The problem does not seem to appear in 4.8.2.
When the problem occurs the following error message is printed to the shell, from which the creator has been started:
Parsing [...]/source.cpp failed: CXError_ASTReadError Reparsing [...]/source.cpp failed: 3
Additionally syntax highlighting does not work correctly, and neither does auto completion, making the IDE nearly unusable.
The following CMakeLists.txt reproduces the problem i have reliably. header.h and source.cpp do not need contain any code.
