Bug ID: 67122
Summary: [5/6 Regression] installed plugin headers not
sufficient
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: plugins
Assignee: unassigned at gcc dot gnu.org

It yields on my system:
In file included from
/usr/lib/gcc/x86_64-linux-gnu/5/plugin/include/hash-set.h:24:0,

/usr/lib/gcc/x86_64-linux-gnu/5/plugin/include/gcc-plugin.h:33,

/usr/lib/gcc/x86_64-linux-gnu/5/plugin/include/hash-table.h:201:15: fatal
error: new: No such file or directory
compilation terminated.
This looks to me like some very basic parts are not working correctly.
Currently the build-essential is updated from 4.9 to 5.2.1, but this problem
prevents the gcc-plugins from working.
At the location gcc-plugin-dev breaks on the "#include <new>" rule:
..
#define TYPED_HASHTAB_H
#include "ggc.h"
#include "hashtab.h"
#include <new>
template<typename, typename, typename> class hash_map;
template<typename, typename> class hash_set;
/* The ordinary memory allocator. */
..
