Fix crash reported in https://bugs.kde.org/show_bug.cgi?id=338649#c20
related to multiple calls of m_source.unicode() where the calls return
different address values.
The solution is to call m_source.unicode() only once:
lib/cppparser/lexer.h
- In class Lexer add private member m_src of type const QChar*.
lib/cppparser/lexer.cpp
- In function Lexer::setSource,
- assign m_source.unicode() to m_src;
- if m_source.isEmpty() returns true then return without calling
tokenize().
- In function Lexer::reset initialize m_src to null pointer.
- In function Lexer::offset return m_src + offset.
- In function Lexer::getOffset use m_src in lieu of src.
This avoids the second call to m_source.unicode() which on newer Qt5
versions may return a different buffer.
