I am able to consistently kill mit-scheme in OS X/X11 when using
edwin by doing the following:
On a new line in edwin, create a literal tab character (e.g. in
Fundamental mode) and then insert several characters. Then,
proceed to insert characters BETWEEN the tab and the last
(non-line-feed) character on the line until the cursor would
normally line-wrap (i.e. the highlighted character is the character
before the '\' line-wrap marker).
I can't reproduce it in my more recent build of Scheme, so this is
almost certainly caused by the bug fixed in 5f1074a. Can you try
building a fresh Scheme from Git, and then building another fresh
Scheme from Git using your fresh Scheme, and see whether the bug
persists? (The two-stage build is necessary to get Scheme compiled
with the a fresh compiler.)

Fix bug: when merging register maps, if a pseudo register was saved
into its home on some of the maps, and not saved on the other maps,
then the resulting map would show that it was saved. Instead, it
should show that it is NOT saved. That's less optimal but correct.
