Description Han Holl 2001-01-10 06:11:39 EST

When compiled with -g3, no virtual table code is generated with
pragma implementation:

File a.h:
#pragma interface

class a {
	virtual ~a();

File a.C:

#pragma implementation

#include "a.h"

a::a() {}
a::~a() {}

main(int , char **)

c++ -g3 a.C


/tmp/ccnMnzgd.o: In function `a::a(void)':
/home/han/g3bug/a.C:5: undefined reference to `a virtual table'
/tmp/ccnMnzgd.o: In function `a::~a(void)':
/home/han/g3bug/a.C:6: undefined reference to `a virtual table'
collect2: ld returned 1 exit status

When compiled without -g or just -g everything is fine.
This is RH 7.0 gcc-2.96-69
