another workaround to switch off flex-mmap is to set the stack ulimit to
'unlimited':
saturn:~> cat /proc/self/maps | tail -7
b7db3000-b7db4000 r--p 00cfd000 03:41 3735973 /usr/lib/locale/locale-archive
b7db4000-b7de1000 r--p 00ccc000 03:41 3735973 /usr/lib/locale/locale-archive
b7de1000-b7de7000 r--p 00cc3000 03:41 3735973 /usr/lib/locale/locale-archive
b7de7000-b7fe7000 r--p 00000000 03:41 3735973 /usr/lib/locale/locale-archive
b7fe7000-b7fe8000 rw-p b7fe7000 00:00 0
bff2c000-c0000000 rw-p bff2c000 00:00 0
ffffe000-fffff000 ---p 00000000 00:00 0
saturn:~> ulimit -s unlimited
saturn:~> cat /proc/self/maps | tail -7
42188000-4218a000 rw-p 00014000 03:41 3433982 /lib/ld-2.3.3.so
4218c000-422aa000 r-xp 00000000 03:41 3434006 /lib/tls/libc-2.3.3.so
422aa000-422ac000 r--p 0011d000 03:41 3434006 /lib/tls/libc-2.3.3.so
422ac000-422ae000 rw-p 0011f000 03:41 3434006 /lib/tls/libc-2.3.3.so
422ae000-422b0000 rw-p 422ae000 00:00 0
bfea0000-c0000000 rw-p bfea0000 00:00 0
ffffe000-fffff000 ---p 00000000 00:00 0
e.g. SuSE defaults to an unlimited stack so flex-mmap is effectively
disabled there.
To set the VM to legacy, for all apps, set /proc/sys/vm/legacy_va_layout
to 1.
