--enable-checking=all hasn't worked for a while. Although your email prompted me 
to write and install patches to fix multiple bugs in this area, the remaining 
buggy suboptions --enablechecking=conslist and --enable-checking=xmallocoverrun 
are more trouble than they're worth to fix, and should go. (GCC's 
AddressSanitizer has made both options obsolete anyway.) Please try the two 
attached patches and then try the above 'configure' line again.

Also, if you use older GCC or unusual GCC flags like '-Og' with 
--enable-gcc-warnings=warn-only (which is the default in developer builds), GCC 
will sometimes report false alarms. Typically I don't worry about these, as it's 
already plenty of work to pacify recent GCC with default options. A superficial 
look at the warnings you forwarded suggested that they're all false alarms.

That one was my fault. Fixed in commits df5ca4f7e66fe075d1ad12a0e2831c4ed91fd186 
and 856806d30fb16dbe695633a2dbe35a8fb4348998.
