You are seeing the effects of this change in slang-2.1.2:

  6. src/slerr.c: When SLang_set_error is called, then add the string
     representation of the error message to the message queue.

Also jed-0.99.19-99 introduced this change:

 99. src/misc.c: msg_error changed to call SLang_verror instead of
     SLang_set_error.  This allows, among other things, exceptions to
     access jed error messages.

In other words, prior to jed-0.99.19-99, the "Top Of Buffer" error
message was not getting propagated to slang-- only the error-code,
which it translated to "Run-Time Error". This is also why the change
introduced in slang-2.1.2 has no effect on versions of jed later than
version 0.99.19-98.

I would not call this an incompatibility-- it is just that the
more informative error message does not get displayed when using an
old version of jed with a new version of slang.

Hopefully these issues have been resolved in the latest version in the
repository.

That file stems from a time when I distributed binaries for
DOS/Windows.  I nolonger do so and as such that file should be
rewritten.
