GDB fails to run program due to KERNELBASE.dll error

I've only started getting this problem recently, and I have no idea when it started occuring/what causes it.

I have this simple test program here:

#include <iostream>

int main()
{
    return 0;
}

but when I try to run it normally, it creates a stackdump.

Stack trace:
Frame     Function  Args
00CBC498  6101D93A (00000198, 0000EA60, 000000A4, 00CBC508)
00CBC5C8  610E2F3F (00000000, 60FC04E8, 00CBC658, 7794ABEE)

When I try to run it in GDB, however, it just plain fails to do so.

gdb: unknown target exception 0x406d1388 at 0x778edae8

This is how my compiler's set up:

g++ -g -std=c++1y -Wall -c main.cpp -o main.o main.cpp compiled... 
g++ -g -std=c++1y -Wall -o a main.o Successfully compiled!

Any idea as to what I'm doing wrong here? The platform I'm using is Windows, and I'm using Cygwin as my development environment.

OF NOTE: I still get the aforementioned GDB error no matter what I have in main.cpp.

ALSO OF NOTE: Here are the additional files in the a.exe executable:

I formerly needed cygboost_filesystem.dll to get boost_filesystem to work, and I need libgcc_s_sjlj-1.dll and libstdc++6 because it won't work without them.

Update gdb to the 7.11.1-1 experimental release version.
