            Bug ID: 65501
           Summary: v850 ICE at c_register_pragma_1, at
                    c-family/c-pragma.c:1317
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joel at gcc dot gnu.org

This occurs during the exception model probe for libstdc++-v3. This should be
reproducible on v850-elf. I think this is the conftest.c based on the
aclocal.m4 file:

    cat > conftest.$ac_ext << EOF
[#]line __oline__ "configure"
struct S { ~S(); };
void bar();
void foo()
{
  S s;
  bar();
}
