Security flaws caused by compiler optimizations?

Optimizations by compiler promise a faster execution... but it's giving up for too much features, and that ends on \\security\\ flaws :
- mainly "crashing.exe"

It's 'security' for the code execution, not an affair about 'hacker agaisnt police'

by using the option 'optimization' you make your code unsafe in a way, with 'to guess' strict environment to launch your app.
if you don't have a accurate ENV for your App, it will be crashing, waiting for another crash and so again and again...

the gain could be effiscient with big big loop, and lot of process to achieve, but your code need a review to be reliable with all optimizations purpose,
all you want to optimize, need 'protecting code by you'.

It's kind of 'balance' between what you have code, and what you have compiled.

The opposite is also true. Running the code in debug can also expose the internals of your app. "Debug" does NOT mean "check everything for security".
