My C code works with -O3 but not with -O0
v1.1 - revised the conclusion a bit When something very basic goes wrong, I have this hierarchy of potential culprits: the compiler buggy hardware OS vendor last and least me, because I don’t make mistakes :) So what doesn’t work ? I am doing a simple cast…

pledge() and unveil() in SerenityOS
This post describes the implementation and use of pledge() and unveil() in SerenityOS.
我现在内心是十分恐慌的。有几个问题。
1,疫情有没有想象中那么快解决
2,怎样减少感染风险
第一点,我不能解决。因为这个事我无法控制。而后者,鉴于这个不懂事的父亲喜欢到处乱窜,而且不喜欢囤积食物,这一点非常不好。
现在是非常危急的时刻,如果哪天大家的口罩都没有了,然后只有少数人有口罩的时候,将是可怕的。我也不知道下一步事情会如何发展。考虑到荆州医院的感染数并没有暴增,事态还不算太紧张。
而且附近有市委和军分区。荆州城乱的可能性不大。
