Description
I tried to add random char combination to QTextEdit and found this case:
#include <QApplication>
#include <QTextEdit>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
wchar_t* errWstring = L"\u065b" L"\u05a6" L"\u0cf9" L"\u0311";
QString errString = QString::fromWCharArray(errWstring, 4);
QTextEdit te;
te.textCursor().insertHtml(errString);
te.show();
return a.exec();
}
The code above causes Q_ASSERT in qtextlayout.cpp at line 1695:
Q_ASSERT((pos == end && glyphPosition == current.num_glyphs) || logClusters[pos] == glyphPosition);
I suspect 3rd character. I also tried to use 'cf7', 'cf6', 'dfa', 'efa', 'ffa' insted with the same result (i mean Q_ASSERT).
