             Bug #: 14702
           Summary: dyninst breaks exception handling
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
        AssignedTo: systemtap@sourceware.org
        ReportedBy: jistone@redhat.com
    Classification: Unclassified


Dyninst instrumentation currently breaks exceptions, for example:

> $ stap --runtime=dyninst -e 'probe process.function("main"){next}' -c 'stap -V'
> Systemtap translator/driver (version 2.1/0.154, commit release-2.0-11-gd5a2f8c + changes)
> Copyright (C) 2005-2012 Red Hat, Inc. and others
> This is free software; see the source for copying conditions.
> enabled features: AVAHI LIBRPM LIBSQLITE3 NSS BOOST_SHARED_PTR TR1_UNORDERED_MAP NLS DYNINST
> terminate called after throwing an instance of 'exit_exception'
>   what():  early exit requested, rc=0
> stapdyn: Warning: child process exited with signal 6 (Aborted)
> WARNING: /usr/local/bin/stapdyn exited with status: 1
> Pass 5: run failed.  Try again with another '--vp 00001' option.

It's not really something we can fix in systemtap, but I'm filing this bug so
we can track it as a known issue.  Dyninst folks know about it too:
