I just had a C source get mangled the same way. I think it looks like part of the decompression table is wrong so stuff is garbled. The problem has been seen to happen when uncompressing many files with one command (ie, "uncompress *"). [Thanks to the Unix Users of Minnesota members who uncovered the bug at a meeting last week] Some large files also have been lost, but I don't yet know if those were done singly or with other files. In my case I was uncompressing some 3.0 stuff, so I know the bug was in the uncompress. Also, a backup of the file was uncompressed fine by 4.0 when it was done alone. I did notify the 4.0 author, and he hadn't heard of this before. Perhaps someone can find a repeatable example for him? The program is wonderful and, unfortunately in this case, quite robust. -- Scot E. Wilcoxon Minn. Ed. Comp.
