According to https://buildd.debian.org/status/package.php?p=libdevel-mat-perl
the package has a test failure on at least i386 and mipsel64el but
maybe the architectures are just random.

There's also an upstream issue:
https://rt.cpan.org/Ticket/Display.html?id=134117

And failures on CPAN testers:
http://matrix.cpantesters.org/?dist=Devel-MAT+0.49


Can't call method "_more_saved" on an undefined value at /tmp/loop_over_bdir-419118-EAl5mw/Devel-MAT-0.49-0/blib/lib/Devel/MAT/Dumpfile.pm line 516.
t/02contexts.t ...........
Dubious, test returned 255 (wstat 65280, 0xff00)
No subtests run

Cheers,
gregor

Control: found -1 0.51-1
Control: severity -1 serious
Control: block 1055955 with -1

Either it's gotten worse or it's just bad luck, but previously built
archs (armhf and armel) are now failing, making this release critical
and blocking the Perl 5.38 transition.

armel has had three retries so far but let's hope it will succeed
eventually. Even in that case I think this should stay RC until some
action is taken.

Guess we could just skip / ignore t/02context.t, or alternatively make
the build fail deterministically on the affected architectures and remove
the existing binaries...

I also noticed that the new failures are slightly different than the
previous ones we (or the upstream ticket) mentioned, and I'm not sure
this fallout is confined to specific architectures.

Luckily libdevel-mat-perl is no key package and has no reverse
dependencies, so it can safely be removed from testing until upstream
finds the time to look into this issue …
