So that's 3 reports of issues with the GIS Internals build(s) then. Still
could be MapServer-based though...

Possibly not related, but I reported an issue to Tamas Szekeres (gisinternals)
back in March against release-1928-x64-gdal-3-2-1-mapserver-7-6-2(dfdda8a

John: What happens if you take WMS out of the equation, so:
mapserv.exe -nh "QUERY_STRING=

GDAL 2.4.4 doesn't create zips so it must be MapServer doing the
zipping in this version at least?
Direct support for zipped shape is a recent GDAL 3 addition, which
MapServer doesn't use. MapServer uses instead a lower level GDAL's CPL

Yes apologies John for hijacking the thread, I thought it could be related to
your issue but looking less and less likely.
Steve's suggestion to use the commandline mapserv -nh "QUERY..." approach
should rule out a few more issues.
Even - the same zip cannot be opened on Linux either (using Ark
Ah, GDAL also changed... Zipping is done by GDAL, so could be a GDAL
related change (there were adjustments in the past regarding ZIP64 that
could result in some bytes being different). Did you try opening the zip
with another utility (like 'unzip' on Linux) ?
This might be then a completely d
Thanks Even, I'll give that a go (the bisect worked well for another issue a
few months ago).
I presume the zipping issue is more likely to be in the MapServer codebase than
in GDAL?
The GISInternals did switch from GDAL 2.4.4 to GDAL 3.3.3 from the 7.4.3 to
7.6.4 branches.

the chance to run a git bisect session, that could probably give a
strong hint of how to fix that.

Working fine in 7-4-3 but broken in 7-6-4 (and current master) - the zip files
are corrupt, although they have an identical size.

Hmmm... I've not run into or heard of this before although I'm not a
windows user. I did a quick sanity check with a mapfile here and the latest
7.4 and 7.6 versions. While not exactly the same setup you have in terms of
versions, they produce the exact same png image.

I'm attempting to upgrade from MapServer 7.6.1 to 7.6.4 via compiled packages
obtained from GISInternals. I'm running it on Windows/IIS and whereas 7.6.1
was generating .PNG tiles perfectly for me, after upgrading to 7.6.4, the .PNGs
being created appear to be corrupt. I can replace the 7.6.4
