--- Comment #1 from nyanpasu64 <nyanpas...@tuta.io> ---
I'm getting the same crash when diffing two shell scripts, but a different
crash when using KDiff3 as a Git mergetool.
The crash occurs on
https://invent.kde.org/sdk/kdiff3/-/blob/1.10.1/src/difftextwindow.cpp?ref_type=tags#L1751.
After hours of fruitless debugging (https://invent.kde.org/-/snippets/2597),
rr, pernosco, asan, I recompiled KDiff3 in debug mode and saw:
>ASSERT failure in QVector<T>::operator[]: "index out of range", file
>/usr/include/qt/QtCore/qvector.h, line 457
All the invalid shared_ptr nonsense is a result of creating an out-of-bounds
pointer and interpreting it as a pointer to Diff3WrapLine {
std::shared_ptr<Diff3Line> pD3L ... }.
