Hi,
Building cmor 2.8.0-2 fails for me in exactly the same place but with
different error codes. This is kfreebsd-i386 with up-to-date Wheezy,
running in VirtualBox limited to 512MiB RAM and no swap:

The linker is killed by OOM-killer, so I also get this in dmesg:

With ktrace/kdump I managed to find this:

It is trying to map a range 0->0x29fa3000 = ~671MiB bytes which is why
it fails in my VM which has only 512MiB RAM. The value being requested
as length here appears to be a pointer.

Maybe it just had more available RAM than the buildds?
