Hi,

I have written a library and an example that compiles (and works) fine when compiled on Arduino and in Debug mode on Visual Micro under VS15, but fails to compile with a bunch of errors when trying to compile it in Release mode.

I believe the problem is a multiline macro definition

#define REP(_pm_)  { \
float dty = _pm_::Duty(); \
float frq = _pm_::PRF(); \
Serial.print(dty); Serial.print("% @ "); Serial.print(frq); Serial.print("Hz"); \
Serial.print(" (");Serial.print(_pm_::TimeCounting()/1000000);Serial.print(")"); \
Serial.print(" | "); \
}
 

that calls static member of a template class, namely the _pm_:uty() call, where _pm_ is template class that contains only static members and is defined later.

If I insert something like 
typedef PWMinfo<0> _pm_;
before the macro definition - it compiles, but this is not the solution. I believe it should compile as it is, since Arduino and Debug mode can compile it without this definition.

Yes, it solved the problem. After adding a simple declaration of a global variable it now compiles in release mode.

Thank you.
