RE: svn-0.30.0-setup.exe trashing the Environment $path as per 0.14.

System is Windows XP ProfessionalBuild 2600 SP1.

The path entry in the registry was truncated to only include the SVN entry.

The previous path entry was just around 1000 bytes in length.

As to what I am using with SVN -- I am using a variety of items [CMD.EXE,
TortoiseSVN, etc].

The "trashing" happened immediately after a fresh install and was verified
by checking the registry entry. I had uninstalled all previous versions of

My gut feeling is that there was a buffer overflow in the code that updated
the registry entry. I.e., the code that updated the path variable did not
have a large enough buffer to handle the ~1000 byte path record. As you may
know, the registry can hold very long paths, but the DOS shell environment
variables appear to be limited to 1023 bytes.
