Subject: Debugging a class or derived type procedure
Date: Thu, 4 Mar 2021 18:51:34 -0800	[thread overview]
Message-ID: <08fb3131-b67e-ec32-c833-aacbafb4721f@charter.net> (raw)

Hi all,

I am using gdb on an application I am working on.  I have set a 
breakpoint to get the following:

(gdb) r
Starting program: /run/media/jerry/TP5/dev/factivate/a.out
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Program mymain begin

Breakpoint 1, m_application::run (me=...) at m_application.f90:57
57        fdata => me%self
(gdb) p me
$1 = ( _data = 0x414b00, _vptr =
     0x406140 <__m_application_MOD___vtab_m_application_Application> )
(gdb) me::_data

me is the passed argument to the class procedure "run".  I am happy that 
I can see this in gdb and it has the notation displayed well enough.  As 
you can see I can print 'me'.

How do I examine " _data = 0x414b00" ?

Any help appreciated?

Jerry
