[Valgrind-users] very few suppressions with '--gen-suppressions=all'

[Matthias A. <gu...@un...>]

Hello,

This is with valgrind 3.14.0 compiled and used on SuSE Linux 12 and 15 x86_64.

I do start our servers with something like this to get the
suppression-hint into a file to sort them out if they belong to our
C-code or to shared libs we do not have under control, for example of
the DBS Sybase or SSL layer:

    /usr/local/sisis-pap/bin/valgrind --version
    valgrind-3.14.0


    LOG=/home/sisis/guru/avs-sup.log
    nohup /usr/local/sisis-pap/bin/valgrind \
          --leak-check=full --show-reachable=yes       \
          --error-limit=no                             \
          --max-stackframe=8000000                     \
          --trace-children=yes                         \
          --leak-check=no                              \ <**************
          --leak-resolution=low                        \
          --track-origins=yes                          \
          --gen-suppressions=all                       \
          $AVSERVER_PATH/AVServer -p $PORT >>$LOG 2>&1   &

I recently updated from 3.12 to now 3.14 and while I got with 3.12 some
500 suppression-hints, esp. of forein shared libs, now I get less then
10 on the first run of the (same) server. Has something changed with
3.14? I found nothing about this in the NEWS file in the source tree.

It seems that '--leak-check=no' disables somehow the generation of the
suppression-hints.

Thanks
