no, you shouldn't need trace-children. the wine-pthread process contains the
Windows executable, rather than running it as a sub-process.

also, helgrind won't work. if it does, it won't be useful as Tom says.

make sure you have the PDB files for the program you're trying to debug..
without them, valgrind-WINE can't tell you where the errors are.

also, make sure you're using the WINE supplied MSVCRTD.DLL instead of one
copied from Windows, otherwise valgrind won't report heap problems... this
implies that you have to be working with a Debug build of your program.

finally, I do have a tarball based on valgrind-2.1.0 which I can send, or
get Jeremy to put on the website. it's not been very heavily tested though,
so YMMV.
