Smaller testcase:
template<typename T>
struct Foo
{
virtual ~Foo() { }
};
int main( int, char*[] )
{
Foo<int> test;
}
rm -f wa.rpo && g++ -c -frepo wa.C && g++ wa.o
The problem is that the linker is demangling symbols, so collect2 can't tell
the difference between the different destructor variants and keeps trying to
adjust the first one when it's not the problem.
You can work around this by linking with -Wl,--no-demangle
This bug was caused by
2011-07-24 Sandra Loosemore <san...@codesourcery.com>
* configure.ac (demangler_in_ld): Default to yes.
* configure: Regenerated.
* collect2.c (main): When HAVE_LD_DEMANGLE is defined, don't
mess with COLLECT_NO_DEMANGLE, and just pass --demangle and
--no-demangle options straight through to ld. When
HAVE_LD_DEMANGLE is not defined, set COLLECT_NO_DEMANGLE in a
way that has the intended effect on Windows.
