The code below the "--- Cut Here ---" line, a slightly edited form of the 21.4 version of tests/automated/mule-tests.el, contains 433 open parens and 433 close parens but XEmacs thinks the parens are mismatched. Here's a formula to reproduce this error: 1. xemacs -vanilla 2. M-x paren-activate 3. insert the text below into a buffer 4. Move the cursor to the paren before the first "when" and you'll get the following error message: No closing parenthesis found. I tried cutting this test case down by removing balanced parens, but I couldn't get it down further. For instance, if you remove this sexp: (Assert (coding-system-p (find-coding-system 'binary))) then the matching parens are found. This error occurs for me in current 21.4 and 21.5, MULE or no MULE. Does anyone else see this? Here is my Installation file for the 21.4 non-MULE build.
