There was such a tool, called Purify.
replyPurify was great until Rational bought it and jacked up the price 10x.
replyThis is what sanitizers do.
replyI know compilers have advanced, but I was wondering about a runtime debug check.
replyA sanitizer is that runtime debug check. The compiler just inserts those checks.
replyOkay. Then I have to assume that they didn't do it for SimCity! Thanks.
replySanitizers come with a lot of overhead, and the tech wasn't readily available in SimCity's day, certainly not for Windows 95.
replyI was imagining more like some kind of primitive CPU mode that sends every single RAM request to a software exception. Something you would normally have turned off but available for truly heavy duty debugging.
replyThat sounds pretty similar to what Valgrind does, basically runs your program in a VM with that kind of instrumentation. The details of how it works are way past the boundaries of my own knowledge though :)
