From looking at the actual changes, my guess is that #149318 has exploded the time taken to run library/alloctests under MIRI.

From looking at the actual changes, my guess is that #149318 has exploded the time taken to run library/alloctests under MIRI.

Looking at timestamps in the build log confirms that the random_patterns alloctest is taking 1.5 hours to run under Miri.

I have a proposed fix at #150947.
