Second, so you're back to the problem of seeing the "start > end" error.  I presume you're still getting the error with the _SDA_BASE_ symbol, so why aren't you adding the '--exclude-symbols' option?  If you exclude _SDA_BASE_ and still get the error, generate a report with '--verbose=all' and look at the tail of the report to see what symbol it was processing when it died; then exclude that one, too.  Or else, build a newer version of binutils and re-build oprofile with that new binutils.

mmm . . . right.  The --exclude-symbols workaround does not work when generating callgraph reports, because even if you're filtering out a given symbol, that symbol still may show up in the calltree for a different symbol, and we don't filter that out.

Coincidentally, I've gotten another report of this very same issue from a user within my company and have been able to reproduce it myself.  I'm still debugging the problem, but what I have found out so far is that we're seeing the problem when oprofile is built with *newer* versions of binutils.  On a sles 10 sp3 system with binutils 2.16.91, it works OK.
