Title: NULL pointer defererence error in HuginBase::ImageVariable<double>::linkWith Status in Hugin: Fix Released Bug description: Hi there We just want to share that the latest version (2022.0.0) of pto_merge causes null pointer error. Here is the output of program with address sanitizer attached. ### Bug Report AddressSanitizer:DEADLYSIGNAL ================================================================= ==3844==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x7f1d38983b07 bp 0x7fff493bd1f0 sp 0x7fff493b6920 T0) ==3844==The signal is caused by a READ memory access. ==3844==Hint: address points to the zero page. #0 0x7f1d38983b06 in bool std::operator==<std::vector<double, std::allocator<double> >, std::vector<double, std::allocator<double> > >(std::shared_ptr<std::vector<double, std::allocator<double> > > const&, std::shared_ptr<std::vector<double, std::allocator<double> > > const&) /usr/include/c++/9/bits/shared_ptr.h:384 #1 0x7f1d38983b06 in HuginBase::ImageVariable<std::vector<double, std::allocator<double> > >::linkWith(HuginBase::ImageVariable<std::vector<double, std::allocator<double> > >*) /home/ubuntu/targets/hugin-2022.0.0_original/src/hugin_base/panodata/ImageVariable.h:184 #2 0x7f1d38983b06 in HuginBase::BaseSrcPanoImage::linkRadialDistortion(HuginBase::BaseSrcPanoImage*) /home/ubuntu/targets/hugin-2022.0.0_original/src/hugin_base/panodata/image_variables.h:93 #3 0x7f1d38983b06 in HuginBase::PanoramaMemento::loadPTScript(std::istream&, int&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) /home/ubuntu/targets/hugin-2022.0.0_original/src/hugin_base/panodata/image_variables.h:93 #4 0x7f1d389a6618 in HuginBase::Panorama::readData(std::istream&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >) /home/ubuntu/targets/hugin-2022.0.0_original/src/hugin_base/panodata/Panorama.cpp:2178 #5 0x56488e0f5975 in main /home/ubuntu/targets/hugin-2022.0.0_original/src/tools/pto_merge.cpp:99 #6 0x7f1d3609a082 in __libc_start_main ../csu/libc-start.c:308 #7 0x56488e0f6c5d in _start (/home/ubuntu/targets/hugin-2022.0.0_original/build/src/tools/pto_merge+0xbc5d) AddressSanitizer can not provide additional info.
