For me it sounds like being related to bug 45199. Does downgrading gcc change anything?
That's what I assumed initially... I've got gcc 7.3.0 installed as well as gcc 8.1.0.
Rebuilding wine-staging with gcc 7.3.0 CFLAGS=" ... -O2" didn't help this specific problem. An identical exception was raised still.
