When execvp() finds a matching entry in the PATH, it doesn't make sure that it is a regular file. E.g. create a "cp" directory in the cwd and make it executable. execvp("cp",...) will try to execute it.

Never write bug reports when too tired. There actually is an entry "cp", I just missed it; it's a directory. This is just another execvp() bug. I thought I was really clever replacing the stat() in the code copied from my APR code by access(), but we obviously also need to make sure that the entry is a regular file.
