I've applied a patch to Cygwin which should workaround what appears to be a compatibility bug in WOW64 on Vista 64. If you want details, see the huge comment in the sources, file dcrt0.cc, get_cygwin_startup_info().
http://cygwin.com/acronyms/#WJFFM Please try the latest snapshot DLL from http://cygwin.com/snapshots/ Note that this snapshot will show weird directory related behaviour when trying to run tclsh, gdb -w resp. insight, or strace. This is the result of another change and has nothing to do with Vista 64.
