Subject: gdb: breaks rustc gdb debuginfo tests

Date: Tue, 21 Feb 2023 21:43:21 +0100

Package: gdb
Version: 13.1-1
Severity: serious
Control: affects -1 src:rustc
Justification: breaks unrelated software

While preparing an update to rustc 1.65 for experimental, we noticed
that the recent gdb update in sid makes rustc FTBFS by causing 5 of its
gdb-integration test cases fail.

our rustc build uses an (arch-dependent) cut-off for the number of "allowed to
fail" tests - for amd64 it is 8, the current version of rustc in testing/sid
(1.63.0+dfsg1-2) had 2 such failing tests when it was initially built, a
rebuild with gdb from unstable causes the fail count to go to 8 - while not
failing the build itself, the errors look problematic enough to me that it
should likely be looked at more closely *before* gdb ends up in
testing/bookworm. it does also prevent us from getting through the backlog of
rustc upstream releases in experimental, since the baseline for rustc 1.65 test
failures is 4, and the 6 additional ones caused by gdb push it over the
threshold.

the same tests are failing for
- rustc 1.65 (not yet uploaded, MR on salsa[0] which successfully built on
17.02. but fails today)
- rustc 1.63 (testing/sid, rebuilt in unstable chroot)
- upstream rustc master (git clone; ./x.py setup (b, n, n); ./x.py tests/debuinfo)

this is the complete output of the failing test cases (from rustc in bookworm
rebuild) including gdb error messages:

---->8----

please note it's possible that it's actually rustc that is at fault, or
something else breaking rustc's integration of gdb (which uses gdb's python
support). most of the test cases and quick debugging attempts are OK, I hope
the errors above give some pointers on what is actually broken.

thanks!

Date: Wed, 22 Feb 2023 19:26:51 +0100

Hi!

I extracted one of the failing tests and the corresponding gdb commands
so that you can more easily (and quicker) reproduce the issue:

https://salsa.debian.org/fg/rustc-gdb-1031745

instructions are contained within as well. changing the triggering
function (multiple_arguments) to either just have the tuple as argument,
or making the signature

 fn multiple_arguments((oo, pp): (isize, isize), (qq, rr): (isize, isize)) { 

(and adapting the call accordingly) makes the problem go away.

just having multiple_arguments with the call as standalone test case
also doesn't trigger the issue.
