从App Store更新到命令行工具6.3后,包含<vector>或<iterator>内部包含<__ debug>的程序将导致文件未找到错误,如下所示.cpp没有什么有趣的,但包含在其中一个包含的标题中.

void testAtan() {
float temp1 = 62981764.0000000000000000f;
float temp2 = (2.14859168E8f * atanf(temp1));
printf("temp2: %.16f\n", temp2);
}
int main() {
printf("FLT_EVAL_METHOD=%d\n", FLT_EVAL_METHOD);
testAtan();
return 0;
}
在OS X上,它会打印出来
FLT_EVAL_METHOD=0
temp2: 337499968.0000000000000000
在ubuntu上,它打印出来
FLT_EVAL_METHOD=0
temp2: 337500000.0000000000000000
任何想法证明这一点以及如何使结果保持一致？
