Centos7, gdb 'GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-80.el7'.
Here's what I do:
- I use gdb -p to attach to a process.
- Set a breakpoint
Now, I realize that I should have set two breakpoints. OK, I hit 'Control-C'. GDB ignores me, it does not come back out to command line.
Do I have to arrange for some signal to arrive at the process I'm debugging, instead?
