I have been working on a project in LSP for some months now 
and suddenly a lot of strange behaviour is occuring.

The project is medium size (around 20.000 lines) ported from
Turbo Pascal. In the last month or two a lot of work has gone 
into the program and it is now in late-beta testing.

Yesterday a link error occured and "Check Link" revealed:
    undefined "THEPORT" (Runtime.lib)
    < repeated 5 times...! >
Naturally I panicked - everything had run smoothly the hole
day and I was only recompiling after a few cosmetic changes.
  Fortunately this mysterious error disappeared after a complete
rebuild of the project.

Today the editor begins to garble in a most disquieting way:
when scrolling a file pagewise, big chunks of code gets 
displaced and after sufficiently long (short) time of scrolling
around LSP bombs. Also when using the search facility text in 
the line below a pattern match is hilited.
  Similiar behaviour was observed two months ago, and after a
few days tracking I then found that compound statements in a
case-statement (i.e. with "begin"s in some of the cases) was the
culprit. Especially when there is a comment next to the "begin"!!
  At other times I have noticed that the editor occasionally
looses a "begin" when you are editing close to it (in the line
below or similarly). I'm not sure whether these events are
connected or not.
  I have looked loosely at a saved file the editor didn't like
with MacTools (which displays the disk contents directly) and
nothing seems to be wrong with the file. Neither is there any-
thing to see in the editor before it looses its grip so nothing
reveals exactly what is wrong.

My system configuration:
  LSP 2.0p1
  Mac Plus with 2.5 Mb
  SystemTools 6.0.2
  GateKeeper and TMON


Prior to these happenings I was quite satisfied with LSP,
particularly its source code debugger.

Hope something can be done about these bugs, so I can rest more
assured the hole project doesn't corrupt before the application
 is on the street
