As I'm not sure there's a reliable way detect the bitness from the test, I've marked it as TODO for the time being (and added your findings to the upstream issue).

It boils down to perl -e 'shmget(0, , 0666) or die' which dies on amd64 but not in i386. Looking further: # strace -e shmget perl -we 'shmget(0, , 0666) or die' shmget(IPC_PRIVATE, 3567587327, 0666) = 5177377 +++ exited with 0 +++ Given % 2^32 == 3567587327 it's pretty clear that the requested size does not fit into 32 bits (shmget(2) takes a size_t) so just its lower bits get passed in. Not sure if perl should protest somehow there. Anyway, seems like the test could just be skipped on 32-bit or something. -- Niko Tyni nt...@debian.org

With some debugging statements: lib/IPC/Shareable/SharedMem.pm 31 my $id = shmget($key, $size, $flags); On amd64 $id is undef, as expected, but contains a value on i386.

Source: libipc-shareable-perl Version: 1.06-1 X-Debbugs-CC: debian...@lists.debian.org Severity: serious User: debian...@lists.debian.org Usertags: regression Dear maintainer(s), With a recent upload of libipc-shareable-perl the autopkgtest of libipc-shareable-perl fails in testing when that autopkgtest is run with the binary packages of libipc-shareable-perl from unstable. It passes when run with only packages from testing. In tabular form: passfail libipc-shareable-perl from testing1.06-1 all others from testingfrom testing I copied some of the output at the bottom of this report. The issue seems to be related to 32 bit archs. Currently this regression is blocking the migration to testing [1]. Can you please investigate the situation and fix it?
