Hi! I have encountered a strange performance while compiling. The problem is; when I change some <PARAMETER> in my <PROGRAM> and recompile it via: g++ <PROGRAM> -o <OUTPUT> and run it: ./<OUTPUT> I get the <Segmentation fault> error massage. OK, but when I recompile it once again without changing anything: g++ <PROGRAM> -o <OUTPUT> and run it: ./<OUTPUT> , the program seems working perfectly well. This is the case only if program is exactly <PROGRAM>, I did not noticed such a behaviour before. Any suggestion? Benjamin Batistic
