Bug#1094260: FTBFS: ./test/tbb/test_mutex.cpp:109: FATAL ERROR: REQUIRE( n_transactions_attempted.load(std::memory_order_relaxed) ) is NOT correct!

Hi.

FYI: I've just got this error while testing a potential upload
for trixie-proposed-updates in my private fork:

 29 - test_mutex (Failed)

So, I believed this was not a problem anymore, but clearly I was
mistaken...

This time I'm Cc:ing the official Uploaders. Do you have any idea
why this could happen?

Thanks.
