5.2.1 to 5.3

The other day, I was reproducibly crashing fresh DrRacket 5.3
processes by invoking the Macro Stepper on a particular file. (Not a
seg fault; Linux out-of-memory killer would kill it after it got to
close to 3GB RAM usage, since I don't use swap space.)
By commenting-out macro uses, I was able to get DrRacket to not crash,
but its RAM usage would fluctuate between 1.5GB and 800MB. However,
after the Macro Stepper rendered this time that it didn't crash, when
I returned to DrRacket main window, the Definitions pane was blank
white (scrollbar still there, and indicating some text about the size
of my program, but no actual text visible in it, nor selectable).
What was confusing was that the program was not very big, and made
only light and simple use of macros. But my attempts to trim it down
to a smaller test case were unsuccessful.
I don't recall seeing problems like this with the Macro Stepper
before. Even really complicated and questionable uses of macros, it
has handled like a champ. I suppose this could be a regression from
5.2.1 to 5.2.
If someone is really interested, I will try to find the problematic
file later tonight/tomorrow.

The message below suggests that evaluating "stepper-tool.rkt" caused… a seg fault. I'm
chalking this up to "oh, DrRacket sometimes crashes", but I admit that it makes me a bit
uncomfortable.
Advice or suggestions?

A file you are responsible for has a condition that may need inspecting.
