(1) in https://bugs.kde.org/show_bug.cgi?id=197915#c9 is a joke: >Julian Seward 2010-07-12 15:58:25 UTC > As per comment #0, adding support for 80-bit floats is low priority, because > (1) AIUI the majority of floating point code is portable > and restricts itself to 64-bit values, The majority of _consumer_ software uses using double (aka 64bit float), but the majority of _scientific_ software (for example the whole NIH bioinformtics software stack or 99.9% of CERNs simulation software) is relying on long long double aka 80bit or 128bit floats (depending on platform, AMD64 uses 80bits). valgrind is useless for such software. Use Rational Purify instead - problem solved if you're professional business, there's unfortunately no alternative for the opensource community.
