Linux: The size of "unlimited" varies by Linux configuration, so you may need to specify a larger, specific number to ulimit (for example, 999999999). On Linux also note that many 32bit Linux distributions ship with a pthread static library (libpthread.a) that at runtime will fix the stacksize to 2093056 bytes regardless of the ulimit setting. To avoid this problem do not link with the -static option or the -fast option. Instead of -fast, use options: -ipo -O3 -no-prec-div -xP . This only affects the 32bit Linux distributions and does not apply to the 64bit Linux distributions. ! N- Y" V) a4 N; C$ R3 T: i* v, n0 x( I* q1 B, E$ t5 `. F* ?)
