Bug#785557: perl: FTBFS on i386 and amd64: itimer problems on buildds?

[Niko Tyni]

Package: perl
Version: 5.20.2-3
Severity: serious
Tags: unreproducible help stretch sid

As discussed in the thread at
 http://lists.alioth.debian.org/pipermail/perl-maintainers/2015-May/004855.html

perl currently fails to build on several i386 and amd64 buildds due
to failing / hanging timer related tests.

 https://buildd.debian.org/status/logs.php?pkg=perl&arch=amd64
 https://buildd.debian.org/status/logs.php?pkg=perl&arch=i386

Kurt (cc'd) says the buildds were recently upgraded to jessie, except
that x86-grnet-01 was running jessie already in late March when
the first failure of this kind happened (5.20.2-3/i386). 

So it looks like the tests only fail when the buildd is running jessie,
but not on every host and/or every build.

So far we haven't been able to reproduce this outside the buildds.

DSA (also cc'd): What's the virtualization setup with x86-grnet-01,
brahms and binet? Is there a difference with babin, which managed
to build the i386 binaries? Are the underlying virtualization hosts
running jessie too? 

Reporting this against the perl version in stable, but I'm not sure yet
if it affects stable buildds. I expect it does, but tagging as stretch+sid
for now. Clearly something somewhere needs to be fixed before a release...
