    Hi all,
    I seem to have memory problem. When I try to allocate memory:
    @double data[104800];@
    I do not get any problems. However, when I increase array size by 10:
    @double data[1048000];@
    the program runs but freezes. Any one has idea how to fix this problem?
    Thank you.

      Hi and welcome to devnet,

      This is not a Qt specific issue. You are trying to create a table of over 8MByte on the stack which is probably too much.

      Such big tables belongs to the heap. You can also use e.g. a QVector which will handle this for you.
