More stacktraces, plus source file & runscript. gzipped, to squeeze them below
file size limit.
I get random crashes while trying to build the trunk source code of Widelands (
http://wl.widelands.org/ ) using Debian Buster and clang 7.0.1.
The common denominator seems to be that execution always goes through
clang::SourceManager::getFileIDLocal during a crash.
== example stacktrace starts ==

More similar stacktraces (and the files from /tmp/) attached.
Unsure if this is a clang bug, but reporting anyway after seeing the request to
do so multiple times. I know that clang can be and regularly is used to build
Widelands => something in my system provokes this, or not a clang bug at all.
