Description Martin Koller 2012-10-21 10:51:31 UTC 
the Qt-Android port needs some fix in
QString::fromWCharArray() and toWCharArray() methods, because
on Android wchar_t == char (for the simplicity of bionic), which makes the checks
in the mentioned methods wrong.
E.g. sizeof(wchar_t) == sizeof(QChar)
which is never true on Android, and leads to Qt thinking it deals with 4-byte wchar_t arrays.
I'd say this also will lead to crashing apps as this methods will access illegal memory.

Reproducible: Always

seems this was only true until Android 2.3
