Hello,

just a short status update. I haven't forgotten this patch, but I've
had some troubles reproducing the issue. To make sure I'm not on the
wrong track, what happened when you tried to dump dmesg on the affected
dump file without the patch?

For me, I crafted a dump file which causes a segfault. Did makedumpfile
also terminate on SIGSEGV? Did it report an error? Or did it just
produce wrong output?

Thanks,
Petr T
