--- Comment #3 from Tom Tromey <tromey at sourceware dot org> ---
Thanks.  I compiled this with the Fedora 29 system g++
and then ran gdb like:

bapiya. /bin/gdb -nx -q
(gdb) maint space 1
(gdb) file tt
Reading symbols from tt...done.
Space used: 10768384 (+1101824 for this command)


I guess 1 megabyte seems a bit high for such a small
program.

Starting uses some more memory, most likely due to
CU expansion:

(gdb) start
Temporary breakpoint 1 at 0x400ac3: file test.cpp, line 8.
Starting program: /tmp/tt 
Space used: 13144064 (+2375680 for this command)

Re-running doesn't seem to add any memory.

(gdb) start
Temporary breakpoint 2 at 0x400ac3: file test.cpp, line 8.
Starting program: /tmp/tt 
Space used: 24752128 (+0 for this command)


What numbers do you see?
