You're right, I didn't read Jim's message carefully enough. I see that 
the AddressSanitizer code suffered some bitrot since I last got it 
working; among other things its output was being discarded on Fedora 25 
x86-64, which at first gave me a false sense of security.... I installed 
the attached patches to work around the GCC problem that Jim reported, 
the improper output discard, and one minor memory leak uncovered by 
AddressSanitizer.  When I run Emacs with AddressSanitizer now, it 
reports some other minor memory leaks, almost all from the fontconfig 
library. I do not observe any problems with SAFE_ALLOCA.
