Ok, so this might be related to bitmaps created during parsing.
If you specify -r2 *or* -r0 the NullGui is initialized, which
does *not* use any renderer.
So, if you can reproduce with Gui enabled (-r1 or -r3) the next
step would be:

        1) try with both AGG and OpenGL (to see if either one
           is doing better)

        2) show some more backtrace to find out what's
           the offending routine (seems a problem related to
           the caching mechanism we've been discussing in the past)
