Less than in sourcecode confuses tags

  If you have a [sourcecode language='c++'] section which includes a single LESS THAN symbol (e.g. in a for loop) and then you have a blockquote section after the [/sourcecode] WordPress keeps eating the /blockquote close tag. pre, code and i all seemed to be unaffected and any subsequent blockquotes. The outline of my post was this: (‘{‘ and ‘}’ indicating “some quantity of”)

  8x — snip — x8

  { preamble }

  [sourcecode language='c++']// A comment
  // Some code
  for ( i = 0 ; i < 10 ; ++i )
  {
  // some stuff
  }
  [/sourcecode]

  Under Windows:

  {
   some output lines
  }

  <b>

  </b>

  Under Linux/Mac:
  `

  {
   some other output
  }

  8x — snip — x8

  The first /blockquote, emphasized in bold (assuming I have any clue at how this is going to get formatted) would get eaten every time I saved no matter what I did until I replaced the < with != which is certainly <i>a</i> solution but is a bad coding practice I don’t wish to encourage.

  Ok – that’s amazing. I carefully replaced the angled-brackets around the tags with XML entities, and the only tags that didn’t wind up marked up in the comment are the bold tags I wanted it to treat as markup… Bleah.

  OK, it should read:

  Under Windows:
  [blockquote][pre]{
  some output lines
  }[/pre]<b>[/blockquote]</b>

  Under Linux:
  [blockquote][pre]{
  some other output
  }[/pre][/blockquote]

  It turns out you can reproduce the problem with a much simpler example:

  [sourcecode language='c++']
  // comment with < symbol
  [/sourcecode]
