OK, memory helping, I finally identified the root cause. This is a bug in
PROJ. Fix submitted per https://github.com/OSGeo/PROJ/pull/1873
While being deterministic, it indeed looks like random in practice. I'm not
even sure the workaround I proposed would work reliably in all situations with
calls to GDAL/PROJ that would have been attempted before (due to caching of
objects inside PROJ context). So either wait for a version with
https://github.com/OSGeo/PROJ/pull/1873 applied, or migrate away from use of
the deprecated +init=epsg:XXXX syntax
