            Bug ID: 25897
           Summary: gdb hangs on "run": ubuntu 20.04 LTS arm (Raspberry Pi
                    2)
           Product: gdb
           Version: 9.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: targa57 at gmail dot com
  Target Milestone: ---

gdb prompt never returns from 'r' command:

mark@ubuntu:~/hello$ cat hello.c

#include <stdio.h>

int main()
{
        printf("Hello, world.\n");
}

mark@ubuntu:~/hello$ cc -g hello.c

mark@ubuntu:~/hello$ gdb --quiet a.out

Reading symbols from a.out...
(gdb) r
Starting program: /home/mark/hello/a.out 

Notes:
Fresh install of Ubuntu
Two upgrades added (apt-get): 'build-essential', 'gdb'
No other changes to installation
lldb attaches and runs normally

--- Comment #1 from Luis Machado <luis.machado at arm dot com> ---
Should be fixed with
https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1927192. The root cause is
armhf gdb not being able to find required symbols to be able to tell if it
should use a thumb breakpoint or a Arm breakpoint.

Please reopen if this is still a problem.
