Appears to be a Beautifier problem


#1

Editing any file and then saving causes a beautifier error which terminates the beautifier pass.
Update #1: Only some files, not ANY file.
Update #2: It appears as if the problem occurs with indented preprocessor statements. For example:
#ifdef DUE
#define xxxx
#else
#define yyyyy
#endif

Though it doesn’t happen for all.
