Ok, in your previous mail you talked about an "exisiting binary" so I assumed you haden't tried with a recompiled one or a recompiled one didn't exhibit the problem. Anyway, you're right and I've overlooked that mred is threaded anyway so in this case it shouldn't matter if __gthread_active_p() prevously returned false-positives or not. The only way I currently can think of the new __gthread_active_p() causing problems would be if now it returned false-negatives. So far I can't reproduce such a problem nor see how that could happen though. It would help if you could debug where mred craches and what __gthread_active_p() returned in this case.
