Bash Version: 4.3.30
Release Status: release

Description:
        at link step there is a conflict between gcc library in
        lib/gcc/i686-linux-gnu/libc.a
        and bash library
        lib/malloc/libmalloc.a
        for malloc and free functions

Repeat-By:
        generation with --enable-static-link

Fix:
        adding option --without-bash-malloc look a simple fix
    but this generate another issue because in file
    lib/sh/shmatch.c there is a reference to sh_xfree
    The solution is to add
    #include "xmalloc.h"
    in file
    lib/sh/shmatch.c

I hope I was clear (and my solution was really a good one)
as it's the first time I report a bug.
Of course you can ask me some details if necessary,
I will do my best to help you.
