This issue has not been fixed in clang 13 as today's build 402f2cae7dcab also fails. I also was able to reproduce the failures with this autogen.input:

I'm using Fedora 33.
What we'd need to track this down is an --enable-symbols build with
debug information, and then a gdb backtrace at the point of SEGV, not
just that unhelpfully symbol-less backtrace generated by whatever
Ideally, gbuild should print gdb backtraces when soffice.bin crashes
during a UITest. What's necessary for that to work is (a) that core
files are written to CWD (depending on distro settings, you may need
something like `sudo sysctl kernel.core_pattern=core`), (b) `ulimit -c
unlimited` in the shell where you run `make`, and (c) not getting
--enable-breakpad or some other unhelpful thing get in the way, I think.
