Sorry for talking to myself...

If I do a (just to not use bytearray, but that makes no difference)
    char *str = const_cast<char*>(strMovement.toStdString().c_str());
    char *str2 ="1.234";

then the result is still:
0x957e284 
"\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\356\376\220"
0x67a5e03b "1.234"

an obviously the 'str' should look like str2.
