bug#7219: Parentheses matching cursor blink in wrong place

bug#7219: Parentheses matching cursor blink in wrong place

[Eric Mullen]

I was editting a LaTeX file, doing homework for a programming languages
class, when I typed in this line:

\textbf{First($<exp>$) = $\{ (, a \}$ }

When I put the final curly brace on, my cursor showed me the position
of the opening brace that I closed, like it usually does. However, it
snapped to the wrong place, the third $ in the line (and not the opening
curly brace right after the \textbf). The problem persists in this
bug reporting buffer, which does not have LaTeX syntax highlighting.

I tried to do this from within emacs, but when I tried to send this, it gave
me this message:
Sending...failed with exit value 1

Thus I am mailing it.

bug#7219: Parentheses matching cursor blink in wrong place

Also, to give you some more test cases, the following lines also are
subject to this bug:

\textbf{First($<exp>$) = $\{ ``('', ``a'' \}$ }
\textbf{First($<tuple>$) = $\{ ``('', ``a'' \}$ }

However, this line is not subject to it (for some reason)

\textbf{First($<expTail>$) = $\{``e'', ``,'' \}$ }

                               ^
You have an unbalanced paren.

That's probably why.

Eric, was that indeed the problem? Or are you still having paren
matching issues elsewhere? If the latter, could you please provide a new
example, starting from emacs -Q, and specifying which version of Emacs
you're using?

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
