--- Comment #2 from Terrence Enger <[email protected]> ---
Thank you, Joel, for reminding me of this bug report in particular and
for the tremendous effort you have been making to triage bug reports.

I conclude that the slowness of my LibreOffice can plausibly be
attributed to configuration parameter --enable-dbgutil and the
resulting use of debug version of STL iterators.  I am setting
bug status to NOTABUG.


Some details, for those who might care ...

(*) With master commit af3030e (2012-12-05), the program took 42
    minutes to get as far as the dialog box "Enable macros", and
    closing the document and the program took 1 hour and 17 minutes.

(*) Looking at callgrind data from the first five hours or so of
    opening the file, I see ...

      - "inclusive" numbers for debug iterators add up to way more
        than the total cost.  I do not know how to extract the
        inclusive cost of a set of functions (i.e., without double
        counting the cost of references within the set).

      - Looking just at the "exclusive" cost of the couple of hundred
        most expensive functions, I see debug STL functions account for
        65% of all the cost to that point.  The classification of
        functions is my rough-and-ready guess based on the part of
        output from callgrind_annotate which fits within the width of
        my screen.
