My program has a nested std::map object like

map < int, set < void *> *> m;

My program coredown in some situation, and I don't know the reason. I suspect the problem is in the nested map.

I only know using pmap to print simple map objects like std::map<int, int>, but don't know how to print more complicated map objects.

If a map is defined as map< int, int > m;, then

gdb pmap m int int

does work, but if a map is defined as

map< int, set < void * > * > m;

then

gdb pmap m int set < void *> *

does not work

Or is the inner `std::set` the problem and `p m` does not work? If so, please comment, then this should probably be reopened, but you should clarify how `p m` does not work, i.e. what goes wrong. – Baum mit Augen Jul 20 '15 at 15:13
if a map is map m , pmap m int int does work, but is a map is map *> m, pmap m int set * does not work – user2366736 Jul 20 '15 at 15:46
I can't see any "nested map" here. – Lightness Races in Orbit Jul 30 '15 at 17:10
