/usr/bin/ld B.10.37 991028
bintuils 2.11.2
>Description:
The following piece of code will crash HP's system linker
(B.10.37) when trying to build a shared library:

  struct X { virtual ~X();  };
  struct Y { virtual void foo(); };
  struct W : public X, public Y { virtual void foo(); };
  struct Q : public W { };
  void bar() { Q q; }

I know it mustn't be gcc's fault as /usr/bin/ld is at
least partly guilty because of it's fatal reaction.
But where is the real problem ?

    Analyzing this bug report again:
    
    - in the PR, you state you are having problems
      with the linker that comes with HP-UX
    - you then go on to say that you are using binutils
    
    Why aren't you using the linker in binutils?
    You should use the binutils ld if you are going to
    use binutils.

 I already do. My original report stated that I am using binutils 2.11.2.
 Quote from compiling with -v:
 
 /opt/gcc-3.0.2/lib/gcc-lib/hppa1.1-hp-hpux10.20/3.0.2/../../../../hppa1.1-hp-hpux10.20/bin/as
 -o /var/tmp/ccppVe6D.o /var/tmp/ccYO5OWi.s
 
 Whereas
 /opt/gcc-3.0.2/lib/gcc-lib/hppa1.1-hp-hpux10.20/3.0.2/../../../../hppa1.1-hp-hpux10.20/bin/as
 -v results in:
 
 GNU assembler version 2.11.2 (hppa1.1-hp-hpux10.20) using BFD version 
 2.11.2
 
 I've played around with the assembler output a bit. Seems like gcc is not
 outputting some symbols which then make the linker crash. gas does
 accept (faulty?) assembler code that is missing symbol definitions (_foo).
 The system assembler says "as: error 7403: undefined label - _foo (7403)".
 But that's something I rather should report elsewhere.
 
         .SPACE $TEXT$
         .SUBSPA $CODE$,ACCESS=0x2c
 
 _FOO
         .PROC
         .CALLINFO CALLS
 
         .word P%_foo
         NOP
 
         .PROCEND
 
 Please reopen this report.
 
 Harri.

    You are better off using GNU binutils.
