I do my C development with optimisations enabled, which means that the C compiler will obey all the rules and requirements of C.  Optimisations don't change the meaning of correct code - they only have an effect on the results of your code if you have written incorrect code.  I don't know about you, but my aim in development is to write /correct/ code. If disabling optimisations helped in some way, it would be due to bugs and luck.

To me disabling optimisations does one slightly useful thing (compiles a little quicker) and one really useful one. It makes the interactive debugger work. Optimised code confuses the debugger, especially when it does things like reorder code, unroll loops, or merge equivalent functions.
Of course I then test with the optimised version.
