(In reply to Mark Millard from comment #22)

Being explicit about the combined conditions for failure
for my test program:

Both tcache enabled and allocations fitting in SMALL_MAXCLASS
are required in order to make the program fail.

Note:

lldb) print __je_tcache_maxclass
(size_t) $0 = 32768

which is larger than SMALL_MAXCLASS. I've not observed
failures for sizes above SMALL_MAXCLASS but not exceeding
__je_tcache_maxclass.

Thus tcache use by itself does not seen sufficient for
my program to get corruption of its dynamically allocated
memory: the small allocation size also matters.
