Summary 07569: avspa: png for avspa crashes mame
Description the available file (attached) crashes mame.

The file I have matches crc32 and sha1 hash of the original file:
CRC32: E186C782
SHA1: 0B2C43E7367064CA7B526B067C8F76ED11EC3A40

As far as I know, it's been around for a decade and it opens in other software. Others say the same, AntoPISA can't seem to repro this with version .218

I've tested 64bit versions from .171 (first where mame ui shows snapshots) and until .188 the same file works.

On version .189 to .193 mame crashes and i did not test more except .215 to .218 where obviously still happens.

In mame .189 one can read:
-PNG/rendering/artwork/output improvements: [Vas Crabb]
(several points follow), please refer to .189 release notes

Mame crashes with the error: "avspa.png: Error reading PNG file"

In order to open mame again, I have to edit ui.ini and clear the line "last_used_machine"
Steps To Reproduce use the attached file as artwork
search for avspa (or scroll over it)

I've attached what the current PNG for snapshots show that is available from progettosnaps file:!WJQD0QTC!HjdA9xBJvPgkxBQVnHraHEhMfYAcDuj__llfmhWb63I - pS_snap_fullset_218 .zip

Inside the snap/7z file, there is an avspa.png file with the following stats:
Name: avspa.png
Size: 32280
CRC32: 7e00a75d
MD5: 92311befaa5d0090bc924286da89bef3
SHA1: c4a9a881fadfd8ed6b254af9691da0cf13d6b1fb

While when I attempt to view the file while in the user interface I do not get a crash, I do get a message printed to console as you mentioned:
avspa.png: Error reading PNG file

Looking through Windows Photo Viewer, it shows quite plainly that it appears to have corrupt data, with a lot of color differences and oddness.

And you are right. I think that file should be replaced and it started happening in .189 precisely because of this (in .189 release notes):

*Detect more invalid PNG files rather than just behaving badly.

Tested the attached file:
Firefox - blank screen
Office 2010 picture viewer - shows with corruptions
Windows Photo Viewer - shows with corruptions
MAME - nothing, but get console message
MAMEUI - crashed.

Antopisa's files are not official - just make a new snapshot for yourself - let the game run to where you want, then hit F12.

Noted. File will probably be replaced by next .219 version, by the way.

Guess we can close this one although, maybe there's a way to avoid the crash and handle such things gracefully? I mean, even if I take a screenshot myself, it can get corrupted for some reason down the line. Wouldn't be a first in ntfs by only copying to another drive!

Thanks for the prompt support.

As far as crashing, not sure what to say. It sure sounds like (as verified by Robbbert) you are using MAMEUI and not the official binary as that is the only form in which the entire emulator is crashing when hitting that corrupt "avspa.png" file. It doesn't happen with produced binaries.

RomKnight, please note that Mametesters bugs must be made against official MAME. Derivative builds such as MAMEUI are unofficial.

I'm going to close this now, since there's nothing wrong with MAME.
