How can I get a memory map out of a core file?

[Bruce Korb]

Hi,

"jmap" looked really nice, but that is Solaris only.
"pmap" is almost what I want, but there's no /proc/pid directory
for my core dump any more.
If there is some GDB command I can use, I haven't found it.
I haven't seen any obvious way to emulate it either.
Surely someone, somewhere has solved this problem.
Anyone know where the solution is hiding?  :)
Thank you.  Regards - Bruce
