valgrind currently does not work on GCC -O2 compiled executables, which contain std::optional use, due to an upstream bug. See https://bugs.kde.org/show_bug.cgi?id=472329 One workaround could be to use -O1. However, that seems brittle, as variantions of the bug were seen with -O1 as well. So temporarily use clang in the valgrind CI tasks, because this also allows to drop a false-positive suppression for: -DCMAKE_CXX_FLAGS='-Wno-error=array-bounds' Also, update the comment in contrib/valgrind.supp to mention the background: * GCC -O2 wasn't tested with the suppressions file, due to the mentioned bug. * Clang-17 (or later) on aarch64 wasn't tested due to bug https://github.com/bitcoin/bitcoin/issues/29635 and the minimum supported clang version is clang-17 right now. * GUI isn't tested, because it requires a debug build, see the prior commit. This means the only tested config right now is the one mentioned in the suppression file.

# This valgrind suppressions file includes known Valgrind warnings in our
|
|
# dependencies that cannot be fixed in-tree.
|
|
#
|
|
# Example use:
|
|
# $ valgrind --suppressions=test/sanitizer_suppressions/valgrind.supp build/bin/test_bitcoin
|
|
# $ valgrind --suppressions=test/sanitizer_suppressions/valgrind.supp --leak-check=full \
|
|
# --show-leak-kinds=all build/bin/test_bitcoin
|
|
#
|
|
# To create suppressions for found issues, use the --gen-suppressions=all option:
|
|
# $ valgrind --suppressions=test/sanitizer_suppressions/valgrind.supp --leak-check=full \
|
|
# --show-leak-kinds=all --gen-suppressions=all --show-reachable=yes \
|
|
# --error-limit=no build/bin/test_bitcoin
|
|
#
|
|
# Note that suppressions may depend on OS and/or library versions.
|
|
# Tested on Debian Trixie system libs,
|
|
# * using clang (only x86_64, see https://bugs.kde.org/show_bug.cgi?id=485276),
|
|
# * and GCC (only -O1, see https://bugs.kde.org/show_bug.cgi?id=472329),
|
|
# without gui (because it only passes with a DEBUG=1 depends build).
