[Bug dyninst/15101] New: [PATCH] Stap sefaults when calling NSS_shutdown() which was not previously initialized


http://sourceware.org/bugzilla/show_bug.cgi?id=15101

             Bug #: 15101
           Summary: [PATCH] Stap sefaults when calling NSS_shutdown()
                    which was not previously initialized
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
        AssignedTo: systemtap@sourceware.org
        ReportedBy: jiri.horky@gmail.com
    Classification: Unclassified


Created attachment 6845

GDB backtrace

Systemtap git version as of 20130105, SLES SP1, 2.6.32.59-0.7.1.du2-default.

Problem: stap segfaults when running probe for NFSD code (see attachment) in
NSS_shutdown(). This is because NSS was previously initiliazed. Please attached
GDB backtrace as an example of such code. 

I also include patch that fixes this behavior. The patch was originally written
by my colleague Lukas Hejtmanek.
