           Summary: emit diagnostics on unwind errors
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sources.redhat.com
        ReportedBy: fche@redhat.com


Roland reports that the runtime/unwind* code catches a bunch
of errors, but does not give a hint to the user about them,
except via -DDEBUG_UNWIND and/or a smaller-than-expected
result array.

It should _stp_warn() instead, and could limit that to one
message per _stp_module and/or thread-id.

commit 57aeedd3b1d7cd2c5a68b54836624990dc84ff6c
Author: Mark Wielaard <mjw@redhat.com>
Date:   Sun Oct 17 22:51:28 2010 +0200

    PR12124 Emit warnings for bad unwind data encountered at runtime.

    * runtime/unwind.c: Turn dbug_unwind into _stp_warn when they indicate
      bad unwind data in binary.

It doesn't always indicate which module, and it isn't rate limited though. So
keep this bug open in case someone wants to add that.

rate limiting can be done - so so - by staprun itself.
