            Bug ID: 91962
           Summary: ice in build_target_expr, at cp/tree.c:488
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

For this C++ source code:

template <typename a> class b {
public:
  void c(const a &);
};
class B {
  void d();
  b<const int *> e;
};
long f;
void B::d() { e.c((int *)f); }

on recent gcc trunk, produces this:

/home/dcb/creduce/dcbTest/bug542.cc: In member function ‘void B::d()’:
/home/dcb/creduce/dcbTest/bug542.cc:10:27: internal compiler error: in
build_target_expr, at cp/tree.c:488
   10 | void B::d() { e.c((int *)f); }
      |                           ^

The problem first seems to occur sometime between revision
276250 and 276350.
