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
