If this is an O32 or N32 application you are limited to 1 GB of virtual memory
per process. Within that memory you have to fit the call stack, DSO, data,
executable instructions and some amount of heap. The arena of course comes
right out of the heap. You can reduce the call stack size with prctl(2), the
default stack size is 67,108,864 bytes for an N32 application.

If you compile 64bit this problem will disappear.
