Bug #: 13419
Summary: Unable to pretty-print map of lists
Product: gdb
Version: unknown
Status: NEW
Severity: normal
Priority: P2
Component: mi
AssignedTo: unassigned@sourceware.org
ReportedBy: mail@milianw.de
Classification: Unclassified

Compile the following code:
~~~~~~~~~~
#include <map>
#include <list>
#include <string>
using namespace std;
int main()
{
typedef map<string, list<string> > map_t;
map_t m;
m["one"].push_back("a");
m["one"].push_back("b");
m["one"].push_back("c");
m["two"].push_back("1");
m["two"].push_back("2");
m["two"].push_back("3");
map_t::const_iterator i = m.begin();
i++;
return 0; // <= break point on this line
// neither "m" nor "i" are displayed in correct way
}
~~~~~~~~~~~
Now run it and see how it's not possible to get access to the contents of the
map of lists in a sane way using the gdb-mi commands:
gdb -i mi ./a.out
break 18 // assumes return 0; is on line 18
-var-create - * m
// now compare this, esp. note the 'value="{...}"'
-var-list-children --all-values var1
// with this
print m
// similarily compare the output of this:
-var-create - * i
// with the output of
print i
