The exactly the same problem+reasons affects not only GNU/Linux gcore but also
native kernel core dumps:
* glibc insists its behavior is correct
http://sourceware.org/ml/libc-alpha/2009-10/msg00001.html
* core dumping in Linux kernel could be fixed but a patch containing similar
deep understanding of link_map was already rejected before so I doubt this
one would get accepted.
Isn't suitable the GDB change for the core file loading never replied here?
[patch] Fix GNU/Linux core open: Can't read pathname for load map: Input/output error.
