ld internal error

[Bernd Jendrissek]

[Here a deal: I'd be happy to provide more details, as long as I stay Cc'ed.]

I have linux binutils 2.13.90.0.18 (built from source) and it crashes.

Trying to build glibc-2.3.2, I found it had failed thus:

>From the message I conclude it's a bug in bfd regardless of the
circumstances.  I have no reason to suspect a hardware bug; the machine
has 103 days uptime and setiathome all day.

Unfortunately I when I run that failing command by hand, it works.

The source of the message: the call to abort():

    936   if (!entry)
    937     {
    938       if (! secinfo->htab->strings)
    939         abort ();
    940       /* This should only happen if somebody points into the padding
    941          after a NUL character but before next entity.  */
    942       if (*p)
    943         abort ();

Well, what do you know?  Not sure which program it was (part of an RPM build)
but something crashed again.  Here's the message:

/usr/src/home/rpmtest/tmp/INST/glibc-2.3.2-i686-pc-linux-gnu/lib/libthread_db-1.0.so:
 /lib/libc.so.6: version `GLIBC_PRIVATE' not found (required by 
/usr/src/home/rpmtest/tmp/INST/glibc-2.3.2-i686-pc-linux-gnu/lib/libthread_db-1.0.so)
BFD: BFD 2.13.90.0.18 20030121 internal error, aborting at pdp11.c line 719 in 
aout_16_some_aout_object_p

BFD: Please report this bug.

And the corresponding code:

   715    else
   716      {
   717        /* Should have been checked with N_BADMAG before this routine
   718           was called.  */
   719        abort ();
   720      }

BTW objdump --help segfaults.  I have binutils ./configure'd with
--enable-targets=all on an i686-pc-linux-gnu machine with GCC 3.2.1
