We make use of the -include parameter of gcc/clang and have a simple header file added before each file for compilation. SonarQube is able to analyze all files with -include in the compile command, but after that phase it treats the special include file as an PCH and trips on it.
With the compile command similar to this:
g++ -include <project>/pre_include.h file.cpp
analysis of file.cpp succeeds (albeit wrongly flags use of PCH in the debug statements)

Looks like the scanner wrongly assumes the file provided with -include is a PCH.
