System name: green-acres
Type and version: SPARC/Classic 7.7Q
Display type: cgthree
What were you trying to do?
use dbx on a sparcstation5 to debug an executable
What's wrong:
dbx immediately gets a segv
What should have happened:
it should have loaded the executable and other relevant information
and displayed the prompt for a command.
Please describe any relevant documentation references:
I tried this on a sparc classic and dbx does not get a segv.
The segv occurs in both the cases where I am attempting to attach
to a running process or when I attempt to initiate the program
from dbx. Here are the commands issued and the result:
green-acres> r ps
ps -deaf | fgrep abs.wish

green-acres> r dbx
dbx - 3627 abs.wish
