Package: libllvm6.0-dbgsym
Version: 1:6.0.1-9.2
Backtraces into libllvm6.0 (in either gdb or lldb-6.0) aren't any more
complete with the libllvm6.0-dbgsym package installed than without it:
they have function names but no local variables or source line numbers.
I don't know how long this problem has existed, but the traces in
#852746 + #851371 (LLVM 3.9) and #868745 (LLVM 4.0, non-x86) show that
at least the source line numbers used to work. It also affects libllvm7
version 7-6 (from buster but tested in sid); current libllvm7 doesn't
have a -dbgsym at all due to #913946.
This _isn't_ an exact match for either #851371 or #913946: it doesn't
have either of their error messages, and the -dbgsym package size is
about right (i.e. not simply empty).
