add -d or -f to the options passed to the gdb run command.
Or start rgw and attach gdb to the running instance, e.g. `gdb -p $pid` or
`gdb -p $pid radosgw`

Hello there,
I am trying to understand the process flow of rgw part of ceph with the
help of gdb, but I am stuck at a place where the program exits when they
call a function global_init_prefork() after this function it is
shwoing that main thread has exited successfully(detail is given below) and
gdb stops , I am never able to make past this step.To get to my function
through gdb I have to cross this function before.
Here is the image

A strange thing is when I put output buffer after that function and run
cluster then the output is coming, but when doing with gdb the output
buffer is not showing (outpur buffer means I writing some text in a file to
check whether the program is reaching that part of the code)
Any suggestions will be of great help :)
