Package: tcl-expect
Version: 5.45.4-2build1
Severity: serious
User: debian-...@lists.debian.org
Usertags: time-t

Dear maintainers,

Analysis of the archive for the 64-bit time_t transition[0][1] identifies
tcl-expect as an affected package, on the basis that the headers could
not be compiled and analyzed out of the box using abi-compliance-checker[2],
so we have to assume it's affected.

However, tcl-expect' shlibs file declares a dependency on a library
package name that contains no ABI information:

$ cat DEBIAN/shlibs
libexpect 5.45 tcl-expect
$

It is therefore not obvious that we should rename the package to
'tcp-expect-t64' as part of this transition.

Looking at the archive, there is a package built from a separate source
package, 'skycat', which depends on this library

Since there is no self-evident thing to do with the library package name
here, we will not be handling this package as part of the mass NMUs.
Instead I am filing a serious bug because partial upgrades from bookworm to
trixie on 32-bit architectures (upgrading tcl-expect without also upgrading
skycat) will result in ABI skew and may result in broken behavior.

Cheers,
mwh
