Re: GDB and MacOS 11.4/BigSur

Hi Simon,
   Yeh, I’ve queued to do the actions for the first paragraph based on your input that few are working on resolving issues for GDB/MacOS.

    When you mentioned " to get patches in a good state and send them to the gdb-patches
list for review.” I thought, well, first order of business would be this (as I saw an individual had an attempt in 10.1 to fix a null-pointer).  Should I first help here?
