Yes, that was it. The Thai font Angsana New (Regular) was corrupt; 
removing it and all the other Angsana TTF files fixed that problem.  Now 
I'm back to debugging, on the Vista machine where gdb actually works 
[1], the original problem with rxvt-unicode which I encountered on W7 -- 
that is, whenever I do anything "interesting" (like, say, simply 
starting vi), my rxvt-unicode terminal crashes with a SIGABRT:

Program received signal SIGABRT, Aborted.
0x00000000 in ?? ()
(gdb) bt
#0  0x00000000 in ?? ()
#1  0x77015490 in ntdll!ZwWaitForSingleObject ()
    from /c/Windows/system32/ntdll.dll
#2  0x757b9aa4 in WaitForSingleObjectEx ()
    from /c/Windows/system32/kernel32.dll
#3  0x00000564 in ?? ()
#4  0x00000000 in ?? ()


No idea why. I have debugging symbols available but...the abort appears 
to occur down in ntdll somewhere, and I have nothing informative in the 
remaining backtrace. Sigh.  I'm pretty much stumped at this point; my 
next try will be to build a completely minimal, zero frills, version and 
see if it works better. If so, then slowly add features back...
