Public bug reported:
Hello,
REPRODUCE
$ qemu-system-x86_64 -s -S -nographic
<wait>
QEMU: Terminated via GDBStub
$ gdb
(gdb) target remote :1234
(gdb) load /bin/ls
(gdb) target exec
A program is being debugged already. Kill it? (y or no) y
No executable file now.
EXPECTED
Enable program to be executed without terminating QEMU.
DISCUSSION
This was already discussed in [1], reverted in [2], however, no solution
is provided.
It worked perfectly in the past, I guess because of [1] and before [3].
Opening bug for this as discussion in mailing list did not attract
anyone and functionality is required. If there is other gdb sequence to
achieve same result it would be great to get it documented.
Thanks,
