Static member functions failing on hp10.20 (egcs 1.1.1)

[Doug Semler]

The following causes the hp linker to core dump on hppa1.1-hpux10.20
It only occurs if the static function is defined in a different module.
It does not appear in pre 1.1.1 releases.  Is this fixed?????  If not,
I humbly submit that this is a show stopper :)

interface.h

class base
{
public:
	static void static_function();
};

class derived : public base
{
public:
	void caller(void (*func)(void));
	void i();
};

-=-=-=-=-=-=-=-
foo.cc

 #include "interface.h"

void derived::caller(void (*func)(void))
{
}

void derived::i()
{
	caller(static_function);
}

-=-=-=-=-=-=-=-

bar.cc

 #include "interface.h"

void base::static_function()
{
}

-=-=-=-=-=-=-=-

baz.cc

 #include "interface.h"

int main()
{
	derived g;
	g.i();
}


g++ -c foo.cc bar.cc
ar rv libfoo.a foo.o bar.o
g++ baz.cc -L. -lfoo
collect2: ld terminated with signal 10 , core dumped
/usr/ccs/bin/ld: Unsatisfied symbols:
   base::static_function(void)(data)

I did a g++ -S on the files using both 1.1.1 and 2.91.57,
the only difference which appears is that in foo.cc (the calling
module), is that when using 2.91.57, base::static_function is
declared an import symbol...
