#145999 - Buggy compilers. Responding to: ???'s previous message |
If changing optimisation levels "fixes" a problem, that almost certainly indicates that your code is making some unwarranted assumption - and that assumption fails at the higher optimisation level.
I have a nice example here of very simple, legal C code that will break completely when run through the IAR ARM compiler at the highest optimization setting. |
