sword25: ERROR: IDAT: chunk data is too large!

• Windows 10 x64

I can launch the game, start a new game, play the opening movie and start the game itself. But if I go into the in game options, it brings up the debugger with the message of:

ERROR: IDAT: chunk data is too large!

I can reproduce this on windows, but not linux.

I searched the scummvm source code and could not find that error string or subparts, so I suspected that it was coming from a required library.

Some searching has shown that this is an error from libpng:

I would suspect from the git postfix that this is either on a daily / nightly build or on a self-compiled build, so we may need to update the buildbot Win32 toolchain with the latest libpng v1.6.35:
