Valgrind report

Question

I used the valgrind command

valgrind --leak-check=full --show-reachable=yes -v

to check for detected and suppressed errors and got a report on

ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 13 from 8)

What exactly does (suppressed:13 from 8) mean?

Answer 1

It means there were 13 separate problems - possibly leaked memory, or (more likely) known access errors - from 8 different locations that were not reported because they are known issues and not in your code. You may be able to alter the suppressions list to see what they are.
