Message-id: To: cygwin AT cygwin DOT com Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from quoted-printable to 8bit by delorie.com id u6VIbvvc004316 Hi, I've noticed that Cygwin related executables (including ones compiled myself) seem to have a base address of 0x100400000, whereas all other windows executables seem to use 0x400000. Is there a particular reason why Cygwin executables need to start so high up? What's going on in the 4GB underneath them? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
