- This problem occurs if the following three conditions are satisfied:
- (1) Out of inline function A is called inline function B.
- (2) No execution instructions are described after the call of inline function B up to the end of the source file.
- (3) Any of the optimizing options -O[3-5], -OR, and -OS is used at compilation.
[Example:]

{
// Processing
}
void inline funcA(void)
{

- Workaround
Use the -ONA option with -O[3-5], -OR, or -OS.
