System: NetBSD sutekh 1.4D NetBSD 1.4D (GENERIC) #0: Sat Jun 26 19:56:52 PDT 1999 ross@sutekh:/usr/src/sys/arch/alpha/compile/GENERIC alpha
Installing new libraries (probably libcurses) breaks the 1.4 vi(1)
binary, and quite possibly other binaries as well.
I have duplicated this problem on both i386 and alpha.
1. install NetBSD-1.4
2. rebuild and install /usr/src/lib from -current
3. vi anthing
6. Notice that your screen is blank.
Updating a shared library should not break old binaries.
This problem probably appeared when 3,562 lines of patches
were made to libcurses on April 13, 1999.
If vi(1) is then rebuilt and reinstalled, the problem "goes
away". However, this doesn't mean things are OK. The fact that
a shared library broke an old binary means that something bad
has happened. This should be fixed or the next release will
break locally built binaries.
