Building a static bash on Linux is problematic for several reasons besides
the mysterious malloc conflict:
shell.o: In function `get_current_user_info':
/usr/homes/chet/src/bash/src/shell.c:1718: warning: Using 'endpwent' in
statically linked applications requires at runtime the shared libraries
from the glibc version used for linking
I suspect the problem with malloc is that there are one or more additional
symbols in the file (malloc.o) that glibc uses to satisfy some internal
reference, which causes the rest of the symbols from malloc.o to be
loaded, which causes conflicts with the already-loaded bash malloc library.

The actual problem is a missing dependency in lib/sh/Makefile:
shmatch.o needs to depend on config.h so it gets rebuilt when
config.h changes. shmatch.o already includes xmalloc.h via
shell.h, which includes general.h, which includes xmalloc.h. Your
editing the file caused it to be rebuilt.
In general, it's good to do a `make clean' before you re-run
configure with different options.
