This might be kind of whacky, but maybe:

set_trace_func proc {|event, file, line, id, binding, classname|
  printf "%8s %s:%-2d %10s %8s\n", event, file, line, id, classname
  print `ps -u #$$`
}

This (on Linux) should print a trace of every line of
your program being executed, followed by some memory usage
information for the process. ... And slow down your app by
3 or 4 orders of magnitude... ;)

Well, just a thought... Like, you could log the output to
a text file, then go back and see where the memory was increasing,
and see if it correlates to any particular part of the code?
