I'm debugging c++ code with gdb. Something is throwing a wobbly, so I hit "backtrace full" to inspect. Unfortunately some of the member variables are instances of class that contain const static fields. There are a lot of const static fields. In addition, these const static fields are themselves instances of said class:
class foo {
public:
int val;
foo(int _val) : val(_val) {}
static const foo FOO_5 = foo(5);
static const foo FOO_6 = foo(6);
static const foo FOO_7 = foo(7);
...
}
(My real code is a font formatting class with presets for bold, italic, black, red, etc)
The result is gdb feeling the need to spit out every const static field of every member of said class (and every member of each memeber, etc). This results in many screens full of the same const static fields being displayed:

My question is simple: How do I suppress const static fields from gdb's backtrace full command? Or even just remove all static fields. Cheers!

How do I suppress const static fields from gdb's backtrace full command?
(gdb) set print static off
102
The full command is:
set print static-members off
It can be abbreviated to:
set pri st off
If not totally sure, when typing it from memory, use the key to autocomplete each value:
set pri<TAB> st<TAB> off
and you will get back the full version to verify, that you are setting off the right thing. Instead of typing it in each session, you can also put it into the file .gdbinit in your home directory.
Unfortunately, gdb doesn't seem to distinguish, whether values are just static or const static. The above command turns printing of both of them off. So, if you have important state in static fields, you'll need to print that manually. That can easily be done with:
print typename::fieldname
even, if you don't have an object of that type handy. Unfortunately, there doesn't seem to be a wildcard like print typename::* or print typename::static.
