<p>Christopher,</p>
<p>CPLFindFile() calls CPLFinderInit() which issues
CPLGetConfigOption( "GDAL_DATA", nullptr). But CPLFinderInit()
runs once per-thread. So a potential theory for what you observe
would be that something runs CPLFindFile() before you call
CPLSetConfigOption("GDAL_DATA", ...). Setting breakpoint on
CPLFinderInit and CPLSetConfigOption should confirm if this is
what actually happens</p>

<div dir="ltr">I'm tracking down a bug with WFS data import in our
app and it seems like the cause is a call to CPLFindFile
returning NULL, looking for a gmlasconf.xml file that should be
in the gdal share directory.
<div><br>
</div>
<div>This is a Mac universal binary app that embeds GDAL as a
dylib and also includes the share files, so we use
CPLSetConfigOption("GDAL_DATA", ...) to configure the CPL. So
we don't rely on any absolute install/build paths or on the
end-user installing their own GDAL. This worked previously but
we recently updated to GDAL 3.3.1.</div>
<div><br>
</div>
<div>The WFS import fails when CPLFindFile returns NULL on
attempt to read that config file, but the bug does not occur
on my workstation, where this copy of GDAL was built. It turns
out this is because CPLFindFile will return the original
location of the GDAL build/install share directory (which
still exists on my system).</div>
<div><br>
</div>
<div>Can anyone offer a theory why CPLFindFile might ignore the
gdal data path and only look in the absolute install path set
when GDAL was built? Here's some debugger output showing how
these functions point to two different directories at runtime:</div>
