Hello, sorry if this has been already addressed. There appears to be a 
bug in XtAppInitialize. I'm running R4 (with all the patches) on a Sun3, 
SunOS 4.0.3.

The following small program demonstrates it clearly. It aborts with an error 
from malloc_debug(). Don't forget to link against /usr/lib/debug/malloc.o.
The error only occurs when "fallback_resources" is not NULL.

Is this a known bug? Is there a work around? Please respond by email; There's
too many messages posted to this newsgroup for me to keep up with any more :-( 

thanks much - jc
