Hi Rachita,
Fixed in 4.0-3.11 (the only change from 4.0-3.9 is attached).
In fact, while testing in a 30-column window, I found another
gdb output problem where an asterisk (pointer) in a data structure
declaration got dropped for some reason, causing next_online_pgdat()
to fail. Anyway, setting the gdb line width to unlimited
fixes
both issues.
Thanks again for catching this,
Dave
