Building libpng16 from source with zlib v1.2.10

Hi,

Since zlib's latest release v1.2.10, I tried upgrading libpng to v1.6.28.

Here's my usual build script, which works with zlib v1.2.8 but not with
zlib v1.2.10:
make clean 2>/dev/null ; ./configure --prefix=/usr/local
--with-zlib-prefix=/usr/local --disable-static
make && make check && make install

The following happens with both libpng v1.6.26 and v1.6.28 (zlib v1.2.10):
[...]

I am not sure if I should report this here or to zlib?

For reference, here is the script I use to build zlib:
make clean 2>/dev/null ; ./configure --shared --prefix=/usr/local && make
&& make install

This is a Debian wheezy with gcc 6.1.0 on one box, or gcc 4.9.2 on another
box.

Best regards,
