Ctrl-Break killing subprocess even though handled in parent process


I have a dotnet windows console application that runs a bash script as a
subprocess using CreateProcess()  under the covers.

My windows app traps Ctrl-Break via SetConsoleCtrlHandler() and handles it
(returning true from the handler).

I execute the script via the command "bash.exe --login script.sh".

Somehow the Ctrl-Break is reaching the subprocess and causing it to be
killed, which is undesireable.

Is there a way to either prevent the Ctrl-Break from reaching the cygwin
subprocess or telling cygwin/bash to ignore it?
