[QGIS-Developer] Crashes on exit

[Andreas Neumann]

Hi Nyall, 

Thanks for the reply. I also experienced quite a lot of these crashes.
Something that often shows up in the stack trace is 

proj_lpz_dist :
proj_lpz_dist :
QgsCoordinateTransform::transformPolygon :
QgsCoordinateTransform::transformPolygon :
QgsCoordinateTransform::QgsCoordinateTransform :
QHashData::free_helper :
QgsCoordinateTransform::addToCache :
QgsCoordinateTransform::invalidateCache :
QgsApplication::exitQgis :
QgisApp::~QgisApp :
CPLStringList::operator char * __ptr64 * __ptr64 :
main :
BaseThreadInitThunk :
RtlUserThreadStart : 

Like in https://github.com/qgis/QGIS/issues/30753 

But I am sure you also came across these. 

Really annoying. Perhaps disabling the crash reporter on QGIS exit on
the release versions would help? Can we enable them just on the master?

It seems to be a really wide-spread issue that a majority of our users have. It would be great for QGIS' reputation if we could fix this/these issue(s). Or has this already been fixed and people don't use the newest versions?
