<HTTP_REQUEST> - ERR_BOUNDS (line 1) invoked from within "HTTP::path -normalized"

Hi Ivan,

The iRule is just

when HTTP_REQUEST priority 3 {
 # Lines setting variables to 0
  set lc_path [string tolower [URI::decode [HTTP::path -normalized]]]
  ...
}

but it runs for every request and only fails for a short period and then goes back to being fine. Unfortunately I can't see if there's any specific request that is causing the problem.
