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
const int strNumTries = 15;
const int strLength = 98;
I suspect your seeing something like this:

where that last line repeats many times before moving on to any other sub functions.
This is not an error, but rather part of the call to
the following is the only gdb output that has anything to do with the array declaration:
8 char strName[strLength][strNumTries];
