What is the bug or the crash?

I have found out that if I use this file https://github.com/PDAL/data/blob/master/autzen/autzen-classified.laz and try to index it with untwine/qgis compiled with pdal 2.0, untwine crashes (I have verified that with pdal 2.4 there's no crash). The problem is that when untwine crashes, there's no error shown to the user and we'll just keep showing the layer extent.

A similar issue already got solved in #48035 - so now we can report errors reported from untwine, but apparently if untwine segfaults (which is hopefully rare), there's no error message.
