Hello, I tried running cygcheck on an executable, but it crashed. As far as I know, cygcheck shouldn't crash, not even on invalid executables (though this one is valid enough, I think). My cygwin installation is updated. All packages are official ones downloaded with setup.exe. I have attached cygcheck.out (cygcheck -s -v -r). The program that made it crash is not a cygwin program, it's a demo, available here: http://pouet.net/prod.php?which=30244 Direct link to .zip: http://www.trackmania.org/fr-041_debris.zip I couldn't attach it, because Gmail thinks it's a virus. Thanks in advance for your cooperation. ============================================== $ strace cygcheck c:/d.exe --- Process 3752, exception C0000005 at 004016A6 $ gdb cygcheck GNU gdb 6.5.50.20060706-cvs (cygwin-special) Copyright (C) 2006 Free Software Foundation, Inc.
