testcase for QString with sprintf
If a QString is created and a function of that object get's called ist must not
be converted to a QLatin1String.
That class has only a minimal set of functions and for example arg or sprintf
is not supported.
testcase_qstring.cpp:21:5: warning: QString(const char*) being called
[-Wclazy-qstring-uneeded-heap-allocations]
QString("").sprintf("0x%02X", 0x1E);
If the (automatic) fixit get applied there is than a no member error.
testcase_with_fixit.cpp:21:23: error: no member named 'sprintf' in
'QLatin1String'
QLatin1String("").sprintf("0x%02X", 0x1E);
