I've had a number of programs crash after recompiling with the 1.33.0 release and eventually tracked the problems down to shared_ptr, specifically the atomic_decrement function provided in sp_counted_base_cw_ppc.hpp.
Try these: inline void atomic_increment( register long * pw ) { register int a; asm { loop: lwarx a, 0, pw addi a, a, 1 stwcx. a, 0, pw bne- loop } } inline long atomic_decrement( register long * pw ) { register int a; asm { sync loop: lwarx a, 0, pw addi a, a, -1 stwcx. a, 0, pw bne- loop isync } return a; } inline long atomic_conditional_increment( register long * pw ) { register int a; asm { loop: lwarx a, 0, pw cmpwi a, 0 beq store addi a, a, 1 store: stwcx. a, 0, pw bne- loop } return a; } -Howard
