We also have an intermittent brace matching problem in our Javelin (Java
Lexer) and Visual Classworks (C++ Lexer) projects. When editing methods
these tools do a check to see that all braces are matched before
committing changes to the underlying source code. We use brace matching
on the first { and then on the last } in the method as a simple test to
see if the braces are matched.
Very occassionally after modifying the code a brace mismatch message is
displayed (even though all braces match) - but if you move the cursor
around a bit (without making any changes to the code) and then try to
commit again the brace matching test succeeds and all is well - the only
thing that has happened is that the cursor has been moved to a different
position - strange!
I'd be interested in any findings in this area.
