Comment(by mdawaffe):

 I can reproduce this on a site with 90 shortcodes installed a large post
 with 62 captioned images (using the caption shortcode) with interstitial
 HTML between each image.

 In fact, if I remove all but the caption shortcode from
 {{{shortcode_unautop()}}}, I can still reproduce.

 I get PREG_BACKTRACK_LIMIT_ERROR.

 Making preg operator matching the shortcode's content possesive solves
 this for my test case.  Patch attached.
