This class is dllexport'ed and has members that refer to classes that
are only forward-declared in the header (such as QRegularExpression,
used in std::vector). GCC and MSVC appear to emit the destructor at the
point where it is used, which I guess is the vtable, which probably
means where the constructor was inlined because I don't see any virtual
overrides. Clang (at least in the form of ICX) appears to emit it at the
class declaration point.
C:\Qt\qt-everywhere-src-6.3.0\qtbase\src\gui\itemmodels/qfilesystemmodel_p.h(94,20): note: in instantiation of member function 'std::vector<QRegularExpression>::~vector' requested here
class Q_GUI_EXPORT QFileSystemModelPrivate : public QAbstractItemModelPrivate

C:\Qt\qt-everywhere-src-6.3.0\qtbase\src\gui\itemmodels/qfilesystemmodel_p.h(94,20): note: in implicit destructor for 'QFileSystemModelPrivate' first required here
C:\Qt\qt-everywhere-src-6.3.0\qtbase\src\gui\itemmodels/qfilesystemmodel_p.h(94,7): note: due to 'QFileSystemModelPrivate' being dllexported
Fix by defining both the default ctor and the dtor out-of-line.
