C++ regsvr gets stuck on function call in static const declaration

I created a header to store a bunch of common constants used throughout my project. They look like this:

static const double MY_CONST = FOO();

The issue is that regsvr gets stuck in my new file. After debugging into regsvr, it appears to get stuck on this line. After killing the regsvr process, I can run the program and step through it. However, this will obviously be an issue down the road since it will have to register successfully upon delivery. I'd rather not have a bunch of static const double definitions in each of these files. Is there a way to get around this? An idea I had was a #define method that is a lambda that returns a static const double

#define MY_CONST (double)[]({ static const double test = FOO(); return test; })

However I can't seem to get that to work. Any suggestions?
