We have found your programs on the web, and after downloading it, the
winzip could not work with the file. Because there is an error in the
header.

Then one of our co-workers found out that by renaming the tar file, the
winzip can extract it without any problem.

i.e., rename dmalloc-4_3_0b3_tar.tar to dmalloc-4_3_0b3_tar.tgz

then everything works fine.

Yuen.
