this can be the problem, see below.

if init is "" then strlen(init) is 0. This means that data is initializad
by new char[0 + 1] and not 30.

...when i > 0 where is input.get() stored?

Data is written into some memory not belonging to right.data

This could be because "<<" reads starting from the pointer you give and
then
continues until a '\0' is found, reading whatever ther is after the end of
your
string (or what you think is the end of your string :-)

Try to allocate a fixed amount of chars and see if there are some
differences
