** Description changed:

  Hi there
  
  We want to share that the latest version (2022.0.0) of pto_merge causes
  heap-buffer-overflow.
  
  The invalid memory allocation may attribute to the excessive values in
  function parameters to the HuginBase::PanoramaMemento::loadPTScript.
  
  Here is the output of program with address sanitizer attached.

Title:
  Heap-buffer-overflow when adding an image in
  HuginBase::PanoramaMemento::loadPTScript

Status in Hugin:
  New

Bug description:
  Hi there

  We want to share that the latest version (2022.0.0) of pto_merge
  causes heap-buffer-overflow.

  The invalid memory allocation may attribute to the excessive values in
  function parameters to the HuginBase::PanoramaMemento::loadPTScript.

  Here is the output of program with address sanitizer attached.
