storage manager unit_tests failing

Unit_tests binary used in regression test300 is failing now.

unit_tests: malloc.c:2379: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1))

Before running unit_tests storage manager enable may be required:
mcsSetConfig StorageManager Enabled N 2>&1
mcsSetConfig Installation DBRootStorageType internal 2>&1
mcsSetConfig -x SystemConfig DataFilePlugin N 2>&1
mcsSetConfig -x SystemConfig DataFileEnvFile N 2>&1
(+restart mdb and columnstore)
