Turns out this was an unhandled exception issue (which was quite obvious
from the stacktrace once I was able to put a breakpoint in cygwin's
abort() implementation). rxvt-unicode was trying to be clever, and
linking only against libsupc++ (that is, using gcc to link, and adding
-lsupc++) rather than linking with g++.
The configure test was apparently simple enough that it passed on cygwin
-- but rxvt-unicode itself was more complex, and died horribly. I
changed it to link using g++ and everything worked fine: both the new
9.15-1 and a simple respin of the old 9.07 release.
I still can't use gdb on my W7 box, tho...
