             Bug #: 13272
           Summary: printf "quoting" broken
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: mjw@redhat.com
    Classification: Unclassified


Since the new PR3217: Compiled printf support went in the following is broken:

$ stap -e 'probe begin { printf("\"quote\\this\"\n"); exit(); }'
"quote\this"

Now results in:

$ /usr/local/install/systemtap/bin/stap -e 'probe begin {
printf("\"quote\\this\"\n"); exit(); }'
