            Bug ID: 16019
           Summary: limit number of similar semantic errors output
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: jlebon at redhat dot com

Similarly to how duplicate warnings are suppressed to not flood the terminal,
the same could be done for errors. E.g. doing:

stap -p2 -e 'probe syscall.* { next }'

when no debuginfo is installed will result in a semantic error for each
unresolved kernel.function probe point (I counted about 141). This is a bit
tricky since the errors are not exactly the same each time, so we can't look
for an exact match (like what I think is done for warnings).
