I'm not using 3.4.2, but in general:

We use extensive optimization in all of our products (we couldn't live
without it).  Without optimization gcc basically creates paranoid
assembly code. With optimization, gcc basically assumes that you said
exactly what you mean when you wrote your code, which isn't always
true. Perhaps the most common problems are variable declarations. When
a variable can change outside the current scope (for example, in an
interrupt), it must be declared as volatile so that the compiler won't
assume that the variable hasn't changed since the last time it was
accessed. That was the most common problem I've run into.
