Yes. "parent process is cygwin" probably means that a.exe was started from bash. The quote character is special for bash; see for example http://linux.about.com/od/bgb_guide/a/gdebgb30t03.htm This means that when started from bash, a.exe gets what's inside the quotes, without the quotes themselves. cmd.exe may behave differently.
