Debugger in C::B. Can't open cygwin.S

Hi I just discovered a quite weird behaviour of the debugger when declaring a simple two-dimensional array. It looks like it can't open a file cygwin.S in the library.

Cannot open file: ../../../../../src/gcc-4.8.1/libgcc/config/i386/cygwin.S

At ../../../../../src/gcc-4.8.1/libgcc/config/i386/cygwin.S:169

An execution without debugging works fine. There is an example of the code:

#include <stdio.h>#include <stdlib.h>int main(){    const int strNumTries = 15;    const int strLength = 98;    char strName[strLength][strNumTries];    printf("Hello world!\n");    return 0;}

Debugger stops on the char array declaration using 'step in' method. So what's the problem it may be?
