qt creator crash because of std::bad_alloc

I have a big header file in my subject which is nearly 2gb.

Qt creator crashes when I open the cpp file which include the big header file and gives me the error "std::bad_alloc()"

The cpptool tries to parse the big header file when it is included in c files without specifying the limit size of the file in file builtineditordocumentparser.cpp ( function BuiltinEditorDocumentParser::updateImpl).

Shall the object sourceProcessor call function setFileSizeLimitInMb before it goes on?

Thank you!
