Joel,
Thank you for the response.
I found this patch
https://sourceware.org/ml/gdb-patches/2012-05/msg00500.html - many
thanks to Abhijit.
1. What is the reason to keep it off main trunk? Is there a chance to
have it changed?
2. What API is available from within a plugin? i.e. how I can access
coredump memory?
