Title: Improper handling of values in HuginBase::PTools::Transform::transform causes assertion error in libpano13 Status in Hugin: Fix Committed Bug description: Hi there We just want to share that the latest version (2022.0.0) of pto_merge causes reaching assertion error, which is improper to the normal execution. The stack execution from the function HuginBase::PTools::Transform::transform() checks NaN through the function erect_lambertazimuthal(), but it causes assertion has failed saying ‘pto_merge: math.c:846: erect_lambertazimuthal: Assertion `! isnan(x)' failed.' Here is the output of gdb results. ### Bug Report (gdb) r Starting program: /home/ubuntu/targets/hugin-2022.0.0_original/build/src/tools/pto_merge ../AFLplusplus/hugin_ptomerge_jpg/default/crashes/id:000242,sig:06,src:001403,time:28753634,execs:1225769,op:havoc,rep:2 1.jpg [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". pto_merge: math.c:846: erect_lambertazimuthal: Assertion `! isnan(x)' failed.
