 Check mbedtls_calloc overallocation
+# This test case exercises an integer overflow in calloc. Under Asan, with
+# a modern Clang, this triggers an ASan/MSan/TSan complaint. The complaint
+# can be avoided with e.g. ASAN_OPTIONS=allocator_may_return_null=1,
+# but this has to be set in the environment before the program starts,
+# and could hide other errors.
