Re: GDB & memory access failure
Hi again,
now guess what! I tried another aproach i.e. i tried to enter:
'break main' or 'break someFunctionName'
and it worked.
And I can in ddd select a functionName (main/whatever) and with the name
selected add a breakpoint (by pushing that button...).
Well that makes me very happy and I'm not going to spend months why it
doesn't work with line-numbers (i.e. break 50), maybe I'll stumble
overit someday.
Hope I haven't wasted anyone's time
regards
