I played a bit with GDB and this seems wrong to me:

I guess bfd_fdopenr is doing something wrong. So probably not an oprofile problem.

This time, the sym structure seems messed up (at least the sym->section).

This problem looks very similar to:
http://sourceforge.net/tracker/index.php?func=detail&aid=1921984&group_id=16191&atid=116191

Did you recompile oprofile against the 2.19 binutils you installed and still get this error? If problem continues, please download latest oprofile code from CVS (see http://oprofile.sourceforge.net/download/\). Then let us know results after building new oprofile against new binutils.

Thanks.

Albert Zeyer - 2009-06-01

Yes, I recompiled it against binutils 2.19 and still have the error (my last build was already compiled against 2.19).

I tried current CVS now and also have the same crash:

I still think that this is a libbfd problem actually and not an oprofile problem.

Again, I have also this:

(gdb) print *sym
$1 = {the_bfd = 0x9dfcf58, name = 0x9dfd9df ".interp", value = 0, flags = 0,
section = 0x109, udata = {p = 0x9e087ac, i = 165709740}}

section again seems to be wrong.

I filled in a bugreport for binutils here:
http://sourceware.org/bugzilla/show_bug.cgi?id=10223

Let's see if they can say something about this.

Perhaps you can give some more information there if needed (I am not that familiar with more details of the oprofile code).

Maynard Johnson - 2009-06-26

Looking at the binutils bug you opened (http://sourceware.org/bugzilla/show_bug.cgi?id=10223), it appears Alan Modra was able to help you fix a build environment problem so that oprofile built properly with binutils. So I will close this bug. Please reopen if necessary.
