exe build with cygwin gcc hanging when running in cygwin terminal - cygwin

Question

I build an exe named DatalogTest.exe with cygwin gcc.
When I try to run this (./DatalogText.exe), I just hangs. I can not kill it with Ctrl-C, suspend it with Ctrl-Z or kill it by doing a kill -9 in another shell.
strace gives this output, and then it hangs:
$ strace DatalogTest.exe
