Dmesg not being dumped

I've recently noticed that when creating crashdumps the dmesg is not
being saved. The error reported is this: "Missing the struct log size
export". I've tested with both kernel 4.1.1 and 3.12.28. My version of
kexec tools is : kexec-tools 2.0.9 released 04 June 2015. The kernel has
been compiled with debugging info so the respective symbol should be
exported but apparently it is not. Any ideas how to debug that?
