Title:
  Strange out of memory on pandaboard

Status in “linux-ti-omap4” package in Ubuntu:
  New

Bug description:
  A GCC trunk bootstrap fails with:

  real	8m9.482s
  user	4m0.680s
  sys	1m37.547s

  Looking at top at the time of failure:

  Mem:    681844k total,   368152k used,   313692k free,     6076k buffers
  Swap:        0k total,        0k used,        0k free,   240456k cached

  /home is mounted over NFS, swap is commented out, make bootstrap after
  a clean boot, /etc/rc.local has:

  sysctl -w vm.overcommit_memory=2
  echo 0 > /proc/sys/kernel/randomize_va_space

  In a different situation, with mem=768M in a previous test I got various issues reported in /var/log/messages

  rsalveti asked me to open a report.
