[Bug remote/15379] New: step corrupts stack


http://sourceware.org/bugzilla/show_bug.cgi?id=15379

             Bug #: 15379
           Summary: step corrupts stack
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: remote
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jan.smets@alcatel-lucent.com
    Classification: Unclassified


As reported here by someone else :
http://sourceware.org/ml/gdb/2011-05/msg00001.html

Applying the patch resolved the issue. It would be a petty if it got lost.

Thanks.
