How did you build GDAL: with internal or external libpng ? Can you provide the end of the ./configure report where it reports all detected elements
building gdal with external libpng version: 1.6.34-1ubuntu0.18.04.1 end of ./configure report:
GDAL is now configured for x86_64-pc-linux-gnu

The ubuntu18_04 configuration in Travis-CI does also have "LIBPNG support: external" with libpng 1.6.34 and the tests pass fine. So I suspect this is something to do with your build (or potentially the particular png you use). In case you try different ./configure options, make sure you 'make clean' before make
@rouault why the internal libpng version is still in 1.2.x ? But the latest libpng has been up to 1.6.x .
@savelovrk7 Rebuild gdal and try add --with-png=internal
cd gdla-x.x.x
./configure --with-png=internal
@rouault how to replace libpng to 1.6.x?
@urmyfaith ./configure --help
and learn the option to specify external libpng

@mloskot I will try to build GDAL 2.4.3 with libpng 1.6.x hope it works.
@mloskot seems works.
I am intergrating opencv and GADL into an iOS app.
Opecv is installed by pod, and GDAL is build into .a file by hand.
Bcz opencv and GDAL both use libpng. But different version of libpng lead to a crash.
Finally I fixed it by rebuild GDAL with the same libpng version which opencv used.
Thanks.
I understood that you solved your problem, there was no bug in GDAL, and this ticket can be closed. Is that right?
Expected behavior and actual behavior.
Expected behaviour: opening png-file. Actual behaviour: error: ERROR 1: libpng: bad parameters to zlib ERROR 1: /tmp/some.png, band 3: IReadBlock failed at X offset 0, Y offset 95 ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 95
Steps to reproduce the problem.
Open png-file with GDAL API.
Operating system
Ubuntu 18.04 64 bit
