Hi Jacek!
Please have a look at
http://kegel.com/wine/valgrind/logs/2009-10-20-01.09/vg-jscript_run.txt
There are a few interesting errors there. The first one (with a
little context from
http://kegel.com/wine/valgrind/logs/2009-10-20-01.09.log) is:
valgrind ... wine jscript_test.exe.so run.c
...
run.c:367: Test failed: lang.js: L"2.5*3.5 !== 8.75"
...

Removing the common bits, the core of that warning is
