--- Comment #4 from Alistair Leslie-Hughes leslie_alistair@hotmail.com --- The OBS server has built wine-staging 5.4, so there must be something else going on. There was a change to correct an issue with the test in xactengine-initial and a copy updates to FIXMES, but nothing else.
Could ccache be returning a bad result? I've had issues recently with ucrtbase being updated which causing linker error at other points because the objects files weren't being recompiled. (not the same error, just suggesting possible caueses).
