[cfe-dev] Combining floatLiteral() Node Matcher with isExpansionInFileMatching() Narrowing Matcher provides unexpected results

[FarSight Studios via cfe-dev]

Hi,

Combining floatLiteral() Node Matcher with isExpansionInFileMatching()
Narrowing Matcher provides unexpected results.
The following matcher:
floatLiteral(isExpansionInFileMatching("include/math.h"))
does not matches "M_E" which is defined in "math.h"

#include <math.h>

int consts(int n){
    double varX = M_E;
    return varX;
}

It matches a single unrelated node:
FloatingLiteral 0x562c409bdaa8 </usr/include/math.h:1184:47> 'float'
0.000000e+00

Am I doing something wrong?
Thanks
