Accessing tmpcstr[0] after that will cause invalid behaviour (and

guaranteed a crash with the Qt4 equivalent on a VS 2005 release build).
und jetzt?
Which means "Et maintenant?" (so google say).
tout a fait
An now, take my solution or remove the const.
will take your solution then
could someone explain it to me?
fromUnicode return a temporary QByteArray; so is the internal char* that
is returned by data(). So a const pointer will stay valid only during
the current context (remember that char * is not a simple pointer in C
and C++). A copy instead of a reference solve the problem.
Am I clear?
Abdel.
the qt docs say:
const char * data () const
