No, but a guess might benefit from more information such as
which tool with which options, what errors are being suppressed, and
what are the new errors that are appearing when adding
suppression entries, ...
And of course, a (if possible small) compilable test case will for
sure help the most.

Also, would be nice to know the version of Valgrind you are using.
Note that in 3.8.1, the suppression matching mechanism was optimised.
In 3.9.0 (not yet released), the leak suppression entries can be
made more precise (e.g. to only match definite leaks).
