Hi all, I found a problem (or unintended effect? or WJM feature?) with the new change that makes gdb work with cygwin signals: 1. start sqlite3 2. ^z 3. jobs -p 4. in separate terminal window, gdb -p $PID 5. c 6. in first window, fg 7. in gdb window, gdb should have caught SIGCONT, c 8. gdb and sqlite3 are now deadlocked (neither responds to ^c or ^z), you have to kill gdb to escape. I realize that messing with SIGCONT is a good way to confuse the app, but (a) I didn't want to (surprise!) and (b) is there a way to make the penalty for forgetting to ignore SIGCONT a little less draconian? Thanks, Ryan -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
