May I ask why you want to use other optimization levels? Do you just hope that your code may run faster, or do you have actual proof (i. e. measurements) that this is the case? It would be interesting if you could share any such measured results.
Not for running faster. I just think: If turn off compiler optimization, some bugs would be analysed easily.
Hm... that does not match my experience. A pretty large percentage of actual bugs is of Heisenbug nature. Changin the buil environment will create a completely different image with different behaviour - you may be lucky, but too often the changes actually side-track you from the actual issues.
Best regards,
