            Bug ID: 141689
           Summary: Crash with trendline using moving average with 2
                    points and type central
           Product: LibreOffice
           Version: 7.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: heiko.tietze at documentfoundation.org
                CC: rb.henschel at t-online.de, thb at libreoffice.org

As in the title, works with 3 points or 2 prior.

/usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../include/c++/10.2.0/debug/vector:427:
In function:
    std::__debug::vector::reference std::__debug::vector<double, 
    std::allocator<double>>::operator[](std::__debug::vector::size_type) 
    [_Tp = double, _Allocator = std::allocator<double>]

Error: attempt to subscript container with out-of-bounds index 1, but 
container only holds 1 elements.

Objects involved in the operation:
    sequence "this" @ 0x0x55d8ea1a98b0 {
      type = std::__debug::vector<double, std::allocator<double> >;
    }


To test, create a line chart, add a trend line, and set the parameter as given.
