It boils down to perl -e 'shmget(0, 999999999999, 0666) or die' which dies on amd64 but not in i386. Looking further: # strace -e shmget perl -we 'shmget(0, 999999999999, 0666) or die' shmget(IPC_PRIVATE, 3567587327, 0666) = 5177377 +++ exited with 0 +++ Given 999999999999 % 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
