Looks like you are just overflowing long, which is 32bits on i386. You are multiplying size in kilobytes by 4K, in 32 bit math, which as it can be easily seen will overflow 2^^31 limit and therefore go negative when maxrss is more than 512K. -Maxim Mikhail Teterin wrote: > Hello! > > I have a program, which uses getrusage() to report its own performance before > exiting. > > I noticed recently, that the ru_maxrss field is sometimes reported negative -- > I don't think, I ever saw this last year, for example...
