Hi Kevin, Thank you for reporting. I guess that the problem depends on kernel configuration, and I want to reproduce it on my machine for investigating. Could you send me your kernel .config file ? And please let me know the kernel version.

It looks like "system_utsname.release" is NULL coming into the strcmp on line 340 of makedumpfile.c .
