[Valgrind-users] Valgrind ignores --tool in VALGRIND_OPTS env var and .valgrindrc?

[Ishwara <is...@sz...>]

Hi
I'm new to valgrind. I wanted to change a default tool to e.g. helgrind by setting VALGRIND_OPTS env variable.
echo $VALGRIND_OPTS prints: --log-file=rrc.log --time-stamp=yes --tool=helgrind
But valgrind keeps running memcheck. Other arguments work, only tool is being ignored.
I get the same result when using .valgrindrc file.
Anyone has any idea how to change the default tool? (not specifying it each time)
