Compiler expected Unqualified-id before numeric constant error

Today debug code, encounter expected Unqualified-id before numeric constant error, code error module appears on a function module,

It is strange that this function module has been compiled many times before, and has not been modified, highlighting errors.

Online check, found that this error is generally in other places there are errors, the compiler error place in another place.

Solution:

Estimates are mostly in header files containing modules, step-by-step fallback versions, found to be in the header file of # include <string> introduced, it is unclear why
