The reason is that there +# is currently no reliable way to make it work, at least on Linux. +# The reason is that memory is limited using RLIMIT_AS, which limits +# brk, mmap and the stack: when we run out of stack, then of course +# we crash. So RLIMIT_AS cannot be used. In principle, we could use +# RLIMIT_DATA, which limits brk only. However, glibc uses mmap when +# it cannot obtain memory from brk (and perhaps in other cases as well), +# but mmap is not limited by RLIMIT_DATA. In summary, RLIMIT_AS limits +# too much (in particular the stack, that should not be limited); +# RLIMIT_DATA limits too little (it does not limit mmap, as we would like +# it to). + +#VALGRIND_BRITTLE_TESTS = memory1 + +#memory1_SOURCES = $(memory1_SRCS)
